The author has not read the novel, just got information from other fanfics, so the possibility that the plot below will be wrong + OOC characters.

----------------------------

0. The beginning:

By the time Kim Dokja decided to help Yoo Joonghyuk's 0th turn began to regress, they didn't know the impact of that decision.

When Kim Dokja left the train, the world decided to create an observer.

A person who shouldn't exist, but exists thanks to Kim Dokja.

One who would protect Kim Dokja without hesitation, but would watch Yoo Joonghyuk when Kim Dokja was not there.

Someone that Kim Dokja and Yoo Joonghyuk wouldn't pay attention to.

An important person but also unimportant to Kim Dokja.

A cloth is created that wraps the child who will live a life he would not have existed.

Lee Gilyong shouldn't have existed, during his lifetimes of watching Yoo Joonghyuk.

Only when Kim Dokja appeared, Lee Gilyong could "live".

------------------------------------------------------------

1. Survive:

Lee Gilyong has always tried to stay alive, hiding from everyone's eyes.

He had survived the neglect of his parents, had survived trying to get food outside, had survived the fire that had taken his parents' lives.

But no one knew it, they just thought Lee Gilyong was a monstrous insect-loving boy who was lucky not to be in the fire when his parents died.

Lee Gilyong survived when the apocalypse began, survived eating monster meat without cooking it lightly, managed to survive in a scenario that no one noticed.

Under the black cloth that was always with him, Gilyong had always avoided the eyes of all the constellations.

But when he survived, Lee Gilyong unconsciously observed someone.

Someone who is an asshole who likes to wear black, with a kindness that is slowly disappearing, with a personality that fluctuates with each lifetime.

No matter how much he wanted to leave at first, Lee Gilyong would always find himself involuntarily observing that person, with a strange murderous desire inside.

When that person is in trouble, Lee Gilyong will secretly help.

When that person wants to die, Lee Gilyong will kill him.

After that, Lee Gilyong will watch the world fall, close his eyes waiting for his end.

Only to then open her eyes, sit inside the subway, with the memory completely gone.

The process will repeat again.

------------------------------------------------------------

2. Mistake after mistake (2th Au).

Lee Gilyong was sure that he was dead.

Dead cannot die more.

Before Gilyong could escape and crush the insects, a silver-haired teenager killed him.

Gilyong was sure his head was already detached from his body by then, unless some miracle made him a Zombie.

So why is Gilyong still sober now?

Gilyong looked above the light, then heard someone walk in.

"Master! The baby is awake!"

Someone's voice rang in his ear, then Gilyong found himself being picked up.

Pick up?

A magnified face of a man in black appeared, trying to stiffen a smile.

...If you change another child, this face will surely scare him.

Gilyong ignored his hand being held up, not at all surprised to see the baby's chubby little hand.

Looks like he was reincarnated as the son of this man.

Gilyong make some small noises, causing the man to laugh.

Smile is much more pleasing to the eye.

After seeing his mother in this life, Gilyong was even more satisfied.

Looks like he will have good parents in this life.

Especially his father, who is "a bit" too protective of him, especially when he sees him playing with his (insect) friends.

(It's a bit adorable, if Gilyong is honest.)

And the first time Gilyong saw the killer who killed him.

Gilyong decided to cry really loudly.

Kim Namwoon was banned from approaching Gilyong for a very long time, to Gilyong's satisfaction.

Sweet revenge.

Gilyong was satisfied with his life, even though he died early.

The only thing that affected Gilyong was his father's face when he was about to die.

His face seemed to have lost his whole world.

Ah, that's good.

He is loved, in this life.

When he woke up again inside the subway, Gilyong looked at the completely changed man, for some reason felt pain in seeing him.

(Yoo Joonghyuk 2th looked at the kid on the subway with Kim Dokja, for some reason thinking of his own child.

His dead child.

Yoo Joonghyuk 2th decided to return to his room, no longer observing.)

------------------------------------------------------------

3. Obsession (41th AU).

Lee Gilyong carried out his plan right, killing insects, then lowered his sense of existence to the lowest, hiding under the chair.

Fortunately, it appears that the other two survivors in the vehicle did not heed the announcement, too excited or stunned by the killing.

〖 Constellation《 Lord of the Abyss 》 stares at you. 〗

And it seems that only one constellation notices him.

Gilyong heard the door open, then felt the person on the other side of the carriage enter.

Then, the moment that person opened his mouth, Gilyong trembled.

It feels cold, like death is near.

Gilyong's eyes fluttered open, then he saw.

That figure in black, felt like someone he really hated, and at the same time different.

The sense of belonging that greeted him, the darkness and coldness that Gilyong pursued.

An anomaly like him, at the same time an existence he hated, but also an existence he liked.

For the first time, Gilyong had such strong conflicting feelings in his heart.

He wanted to kill that man.

He wanted to follow that man.

Gilyong had decided to follow the man, lurking in the shadows, knowing through the little bugs that followed him.

(Meanwhile, Gilyong felt himself getting stronger, slowly being brought up to some terrifying position.

"King of Wanderers" they called him.

It's strange, how can they call a child their king?

But Gilyong couldn't ignore them, especially the tired black-haired teen named Han Donghoon.

The teenager reminded him of someone, but Gilyong couldn't remember who.)

Gilyong saw how that man took advantage of people, saw him throw away all his humanity, saw everyone around him die.

That man is like a machine, only watching for his own optimization.

But, for some reason, Gilyong felt that the man shouldn't be like that.

Interesting, how contradictory.

Then Gilyong was there.

When that man sacrifices the last girl to follow him, to help him in the past.

When the man confessed his existence.

Regressor?

If that's the case, is the man Gilyong is following now just a part of that man?

Gilyong was curious, curious about the other parts of the man.

Gilyong is a bit curious, can the man survive to the end of this regression?

If that man started another regression, what would this world be like?

All of those questions culminate when Gilyong realizes how tired the man must be, in this regression.

If the man was the main character in a novel, Gilyong knew, this regression of the man would be the most hated.

Perhaps his other regressions will have a different attitude towards that man, like the conflicting feelings Gilyong felt in the man.

But then, when he saw the person who completely resembled the person he hated the most, Gilyong would surely hate that person, doing everything he could to avoid or kill that person.

(Gilyong doesn't know that, in the end, Gilyong will always be watching that person, no matter how he changes.)

Funny how, the contradiction has made Gilyong follow that man, until now.

And at the moment that the person was completely down, completely exhausted, Gilyong decided to take action.

Gilyong killed that man.

Gilyong hugged the body that gradually became cold, mesmerized watching their world slowly turn red.

Oh.

That man is truly the protagonist of the world.

Without him, the world would fall.

Gilyong put the man's head on his lap, gently patting his head, like someone else did.

"Good night, Yoo Joonghyuk."

(Yoo Joonghyuk 41th looks at the kid clinging to Kim Dokja's feet, shivering.

That kid, reminded him of the boy who killed him.

But strangely enough, Kkoma 41th had no desire to kill that child, just a strange familiarity.

Those strangely sad and tender eyes always appeared in his mind.)

------------------------------------------------------------

4. Aspiration (999th Au):

How does it feel when you get through the first scenario, only to then faint and suddenly receive a bunch of your own memories?

Lee Gilyong expressed, he wanted to kill himself, thanks.

But because of the obsession with that man in black, Gilyong got out from under the chair, pulling out a black cloth from nowhere.

Gilyong had covered that cloth, his body gradually disappeared and emerged.

He headed to the place where there was the most uproar.

Just a little, he'll just look a little.

Then he will finish this round.

Lee Gilyong was looking forward to seeing a Yoo Joonghyuk with a new personality, or the closest regression-like personality.

Lee Gilyong was looking forward to seeing a Yoo Joonghyuk rise again, continue his journey, or a frantic and desperate Yoo Joonghyuk.

Lee Gilyong was looking forward to seeing a lost Yoo Joonghyuk, whose mind was so foggy that he didn't notice a child had followed and helped him survive.

However, the Yoo Joonghyuk that Lee Gilyong saw was someone with a tired temperament all around, like an old person who had been through so much.

That's also true, in a way.

At least, this time Yoo Joonghyuk decided to collect his group.

But the strange thing is, this time, he is defending them in every way, different from all previous regressions.

Lee Gilyong knows, that throne is not good.

Lee Gilyong knew it, the man knew it too.

So why is he sitting up there?

The answer is very simple.

Lee Gilyong glanced at the crowd below.

It's because of them.

The people in his group, he decided to protect with all his might this time.

Loved and cherished by Yoo Joonghyuk.

At that moment, Lee Gilyong had a strange feeling in his heart, but he quickly pushed that feeling down.

Because Gilyong knew, he was never part of that man's group.

Lee Gilyong was destined to be alone, never accepted.

Regardless of the regression, Gilyong always dies alone, along with the world.

Turning around, Gilyong climbed onto Titano.

"Let's go, Titano."

Lee Gilyong said, not watching the story continue.

Gilyong was very tired already.

All those memories weighed heavily on him.

He was tired of living watching one person.

Lee Gilyong was planning to commit suicide after seeing Yoo Joonghyuk.

But the habit cannot be broken, especially with a completely new Yoo Joonghyuk this time.

When he watched the second choice appear in front of him, then looked at the man standing in the distance, Lee Gilyong did not hesitate to press on the familiar Constellation above.

"Nice to see you again, Abaddon."

Then, ignoring the number of messages that were bombarding frantically, Lee Gilyong got closer to the group.

With his small body now, no one noticed him.

So Gilyong stood near them, deceived himself into being one of the group, then left before they found out.

Gilyong still receives news from the man, while surviving easily from past experience.

In the end, Gilyong was still stalking the man himself.

Seeing that person sacrifice everything, even his soul, Lee Gilyong was...envious.

How funny.

Lee Gilyong is the one who shouldn't be jealous of that.

Because he chose to leave that man in the first place.

As they left, Lee Gilyong looked at the abandoned man, waiting for his own death, his feet involuntarily taking a step forward, then stopping.

〖 Constellation《 Lord of the Abyss 》looked at his precious incarnation. 〗

"Sorry, Abaddon."

"Let's meet again, at the new regression."

The teenager smiled, then continued walking.

That man was already blind, lost both legs and an arm, and his soul was weakly torn in his body, so Gilyong didn't worry about being attacked by that person.

Gilyong hugged him, and like the 41st regression, put the man on his lap and gently combed his hair.

Gilyong felt the man's breathing getting slower and slower, waiting for his death.

At the moment his breath stopped, Gilyong muttered.

"Good night, Yoo Joonghyuk."

It's amazing to see that the world didn't fall apart after Yoo Joonghyuk died.

Perhaps, this world is special?

But that didn't help, because Gilyong knew, he would die after that man.

But as he watched the shooting stars begin to appear in the sky the other night, with his breath slowly fading away, Gilyong couldn't help but make a wish.

A wish that Gilyong has always wanted.

A wish had always followed him when Gilyong looked at Yoo Joonghyuk in this life.

He wished he could have a family like that.

Like family in the very old memory he used to have.

(Yoo Joonghyuk 999th looks at the kid next to Kim Dokja, a sudden feeling of guilt creeps in.

Like, he overlooked something precious.)

------------------------------------------------------------

5. Give away:

Hiding under the black cloth, Gilyong watched the lost man walking around.

Flying in front, Gilyong looked into the man's eyes.

His eyes were completely lost in light, staring with a lot of emotion and heavy fatigue.

Blinking, Gilyong looked at the script that appeared in front of the man, then looked at the man again.

Sighing, he reached out and grabbed the man's lapel, pulling him on a mission.

Why couldn't he just ignore this person?

Gilyong wondered, looking at the mechanical man through the script.

Why does he care about this person?

Gilyong wondered, pulling the man away from the chase.

Why....

Gilyong looked at the man who was desperately kneeling in front of the last wall, sighing.

He took off the black cloth that had always been with him since Yoo Joonghyuk started regressing.

Gilyong knew this decision would kill him instantly.

Gilyong knew that this decision would make his next life even more difficult.

But Gilyong couldn't ignore that man.

The person who was once killed, saved, cared for by him....

The person who was...his father.

Yoo Joonghyuk felt a thin cloth draped over his head, a soft childish sigh in his ear.

Yoo Joonghyuk turned his head, but no one was there.

When he took the cloth down, a message appeared in front of him.

【 Item information:

Name: The Observer's Cloth.

Review: Relic ■■.

Description: A cloth woven from the universe and a part of ■■ that creates it, its only function is to help you see a story at the closest and farthest place without being hurt and also won't leave you until you give it to someone else, as the owner of the cloth, what will you do?

*Put on the cloth, you can hide yourself from everyone's eyes. 】

Clutching the cloth, Yoo Joonghyuk made a decision.

(In the future, Gilyong looks at the black cloth like a mini-universe on Secretive Plotter, wondering why the cloth feels familiar.)

------------------------------------------------------------

6. ■■ of the Oldest Dream (Au):

At first, Oldest Dream was unaware of Lee Gilyong's existence.

That kid isn't in the 《Three Ways to Survive》, why should he care?

But, starting from the 41st turn, his dream was malfunctioning.

Instead of seeing Yoo Joonghyuk move to another regression immediately, the teen god found him still in the 41st regression.

The King of Wanderers, who killed Yoo Joonghyuk, a teenager most like the Oldest Dream.

Hugged Yoo Joonghyuk and put his head on his lap.

With insect corpses all around, brown hair tangled in the wind, black robes of starlight drooping over both of them, from behind the mask, a voice rang out.

"Good night, Yoo Joonghyuk."

After that sentence, the Oldest Dream returned to Yoo Joonghyuk.

But that statement left an imprint on his mind.

Then, as the story goes on, Oldest Dream instinctively searches the text for the boy's existence.

But nothing.

That teenager never existed.

The King of Wanderers is always a different person in each of Yoo Joonghyuk's regressions, which cuts the clues about the teenager.

The Oldest Dream got bored and decided to continue the story.

The teenager was forgotten by him.

But his imagination betrayed him.

Yoo Joonghyuk 999th didn't know whose footsteps came next to him when he died, even the Oldest Dream didn't know.

But that brown-haired boy appeared in his mind, and the imagination that made the person appear was the teenager.

The Oldest Dream found himself being held back, like in turn 41.

The black cloth covered his whole body, making the teenager seem to melt into the universe, the cloth covered his face, making it impossible to see clearly.

He hugged Yoo Joonghyuk, gently combing his hair, until he died, that familiar voice sounded again.

"Good night, Yoo Joonghyuk."

The oldest dream woke up, the boy's voice still ringing in his ears.

He could almost feel the boy's hand gently caress his head.

From that moment on, his imagination went wild.

He began to imagine the teenager surviving somewhere in the corner, watching Yoo Joonghyuk like him.

His companion in that world.

But the novel never appears the brown-haired teen, even when appearing in turn 41, the teenager is only briefly introduced as the "King of Wanderers".

Just a tool to kill Yoo Joonghyuk turn 41.

The Oldest Dream, however, found himself amused by the idea.

Like the brown-haired boy that was his own character created from him.

If so, did he come up with a name for the boy himself?

The Oldest Dream saw myself opening a new page.

He began to draw about that teenage.

A teenager like him, but strong and able to hide, can survive the apocalypse.

That's right, there must be another way for teenagers to keep a close eye on Yoo Joonghyuk?

Insects, that would be insects, the most difficult to notice, when the teenager first appeared, beside him also appeared insects.

...

The oldest dream watched the page gradually take shape, happily looking at the character on it.

Finally, the name....

The Oldest Dream thought of taking his surname, then shook his head in refusal.

There was no need for anyone other than him to take the monster's surname.

Thinking of taking Yoo Joonghyuk's surname, Oldest Dream shook his head again.

No, Yoo Joonghyuk is his own, and the teenager is not Yoo Joonghyuk's child either.

Finally, Oldest Dream thought of his mother.

Surname Lee...sounds fine, there are many Lee characters in the novel.

Oldest Dream wrote "Lee" in the boy's name.

Then he noticed that his hand automatically wrote the remaining word.

Lee Gilyong.

Oldest Dream looks at the name, and feels right.

It was the name of the teenager.

Oldest Dream tore off the paper and put it in his pocket, happily hugged the notebook, and continued to sink his dreams, with a teenager's voice appearing in his head.

"Good night, Dokja-ah."

The oldest dream was dreamed, then his dream was severed.

Someone has infiltrated here.

In the moment of fear, he almost had the feeling that someone was guiding him backwards.

He did not notice the gentle, invisible embrace of someone who had always been by his side.

The Oldest Dream hugged himself, and when he heard a child's scream, he couldn't help but look in that direction.

A brown-haired child, like his "Lee Gilyong", appeared inside the subway train.

The Oldest Dream thought he was dizzy, but before he could look closely, another presence appeared before him, and he was afraid.

As he was taken away, young Kim Dokja couldn't help but turned his head, over the shoulder of the unfamiliar yet familiar Hyung, looking behind him.

But the subway door was closed, blocking his view.

The paper in his lap had disappeared.

(In the future, when completely comfortable with her new family, Kim Dokja goes to the library and sees a child.

A brown-haired child, hidden from everyone's eyes, engrossed with the insect book in his hand.

And Kim Dokja knew, it was his Lee Gilyong.

...Joonghyuk-hyung won't mind adopting another child right?

Ps: The child was completely lured to follow him when he saw Kkoma 999th in his hand, is that a good thing?)

------------------------------------------------------------

7. Observer of Oldest Dream:

"Lee Gilyong" knows he's not human.

He was just a character created by the greatest and weakest creator.

The real Lee Gilyong was a weak child, but somehow managed to survive the apocalypse that the Oldest Dream dreamed of.

"Lee Gilyong" looking at his slowly condensing body, then at the sleeping teenager clutching his notebook.

"Lee Gilyong" is a ghost, created from the imagination of the Oldest Dream.

And the only mission of "Lee Gilyong"....

Looking out the window, Gilyong watched the image gradually turn from the universe into a "movie".

Is to observe and bear all things, to accompany and protect the Oldest Dream when he "dreams".

"Lee Gilyong" carefully placed the Oldest Dream's head on his lap, covered him with most of the large cloth, then watched the "story" he was dreaming about.

"Lee Gilyong" will never be bored by watching a person die again and again, because that is what the Oldest Dream established him.

"Lee Gilyong" is an observer who follows the story on behalf of the Oldest Dream.

So he watched.

Watching that person die over and over again, each new life is to change personality, find a way to reach the final ending.

Unlike the Oldest Dream, "Lee Gilyong" was able to find the person who had a part in his birth.

It was a child.

And "Lee Gilyong" is a teenager.

....Perhaps his creator is a bit stupid?

"Lee Gilyong" raised his hand to pat his head The Oldest Dream, worried about his small head because of Yoo Joonghyuk, which is becoming more and more stupid.

In the hands of "Lee Gilyong", Oldest Dream relaxed even more, rubbing his head closer to him.

"Lee Gilyong": ...

Never mind, it's okay to be stupid.

"Lee Gilyong" thought, back to watching "screen".

Until the body starts to fade, "Lee Gilyong" carefully lifted the Oldest Dream, so that he leaned against the chair.

By the time the Oldest Dream awoke, the warmth that had always been with him had disappeared, leaving only the cold inside the subway train and the notebook with him.

"Lee Gilyong" looked at the Oldest Dream in bewilderment, couldn't help reaching out to pat his head, only to have his hand slide over the head of the Oldest Dream.

Ah, that's right.

I, from the beginning is not real....

"Lee Gilyong" thought, watching the Oldest Dream immersed in the story again, until he "dreamed" again.

While the Oldest Dream slept, "Lee Gilyong" condensed again, continuing to cover him with a cloth, continuing to watch the people on screen fight for their lives.

"Lee Gilyong" always thought this would go on forever, until the day this place was infiltrated.

"Lee Gilyong" sees someone who is most like the Ancient Dream, more mature and wearing a white robe.

But when that person drew his sword, spread his wings, and headed towards them, "Lee Gilyong" was on alert.

"Lee Gilyong" embraces the Oldest Dream, a protective shield is erected, protecting him from the people outside.

But then someone appeared, and "Lee Gilyong" released the invisible hug.

It was the Yoo Joonghyuk they had been observing for so long.

"Lee Gilyong" watched the person move forward, his sword cutting through the hurtful words affecting his creator, then approached them.

"Lee Gilyong" watched as people who seemed familiar appeared, gently talking to the Oldest Dream.

They decided to take him away.

"Lee Gilyong" caught a glimpse of the real Lee Gilyong, then continued walking beside the Oldest Dream.

"Lee Gilyong" was half expecting the Fourth Wall to stop him from leaving, but before the door closed, "Lee Gilyong" walked through.

Before the light hit him, darkness was already over.

...

Lee Gilyong knew he had to find someone.

Someone who is weak, loves to read and is a bit stupid.

Someone he should protect.

But Lee Gilyong had no clue about that person, other than reading the book.

So he started walking into the library, when he could leave alone.

(After all, his "parents" wouldn't care if he disappeared.)

While searching, Lee Gilyong also found interesting books, then immersed himself in reading.

Lee Gilyong always thought the search would take a long time, but a few days later, a teenager came to him.

Lee Gilyong looked at the teenager, and knew.

That's him.

Of course, the plushies number 999 in the boy's hand also attracted Lee Gilyong's attention.

For some reason, Lee Gilyong both felt like chasing after the teenager and wanted to hold the plushies with the number 999 on the boy's hand.

And the face of the man whose face resembles a plushies in a teenager's hand when he saw Lee Gilyong was a bit interesting, so was the plushies number 41.

The fact that all can move is even more interesting.

Gilyong thought, enjoying being hugged by Kkoma 2th with his small body.

His favorite is definitely Kkoma 2th, which doesn't need any explanation.

(Combating Hyung with the man who would later be his "adoptive father" was the most interesting.

And Gilyong definitely won't let that man date Hyung until Hyung is old enough.)
