Jinpei and Kosu were sitting in the waiting room of the hospital, waiting for their turn to get their regular health check. Jinpei was nervous, as he always was during check-ups. Kosu, on the other hand, was relaxed and flipping through a magazine.

Suddenly, Jinpei's face turned pale as he saw his ex-boyfriend, Dr. Yamamoto, walking towards them. They had broken up on bad terms, and Jinpei had never expected to see him again, let alone at the hospital where he was getting his health check.

"Hey, Jinpei," Dr. Yamamoto greeted him, smiling professionally. "I'm your doctor today. Let's get started."

Jinpei tried to keep his composure, but he couldn't help feeling uncomfortable. Dr. Yamamoto asked Jinpei to follow him to the examination room, leaving Kosu in the waiting room.

As Jinpei laid on the hospital bed, he couldn't help but feel a knot in his stomach as Dr. Yamamoto entered the room. They hadn't seen each other since their tumultuous breakup a few years ago, and the sudden reunion was unexpected.

Jinpei had always regretted how things ended between them. He knew he was too conservative and often suffocated Yamamoto in their relationship. But at the time, he couldn't help but prioritize his work and studies over their love life.

Yamamoto, on the other hand, had always been ambitious and focused on his academic career. He resented how Jinpei made him feel unimportant and neglected in their relationship, leading to their explosive breakup.

As Yamamoto conducted the health check on Jinpei, there was an uncomfortable silence between them. But eventually, Jinpei mustered up the courage to break the ice.

"Hey, Yamamoto. It's been a while," Jinpei said, trying to sound casual.

Yamamoto simply nodded in response, his face stoic.

"I'm sorry about how things ended between us. I know I was too focused on my studies and work, and I neglected our relationship," Jinpei continued, his voice softening.

Yamamoto sighed, finally breaking his icy demeanor. "It's okay, Jinpei. We were just too different. You were too conservative, and I needed more excitement in my life. We were never going to work out."

Jinpei nodded, understanding where Yamamoto was coming from. But a small part of him couldn't help but wonder if things could have been different if they both made compromises and worked on their relationship.

As the health check continued, Dr. Yamamoto looked at Jinpei's test results and became concerned. "Jinpei, your magic particle density level is extremely high. This could be dangerous for you and those around you. We need to do more tests to figure out why this is happening."

Jinpei's thoughts were momentarily interrupted by the doctor's findings. His magic particle density levels were dangerously high, which could potentially lead to magical overload and affect his mental and physical health.

Dr. Yamamoto furrowed his brow as he looked at the readings on his computer screen. He had run several tests on Jinpei, trying to find out why the young man had such a high density level of magic particles in his body.

But no matter what he did, he couldn't find a clear reason for it.

"I'm sorry, Jinpei," he said, looking up from his screen. "I don't know what's causing this. I've never seen anything like it before."

Jinpei's expression darkened with worry. "Is there nothing you can do?"

Dr. Yamamoto shook his head. "I'll keep researching and see if I can find any clues, but for now, there's not much we can do except monitor your condition."

Jinpei looked on with concern. "Is there any danger to my health or safety?"

Dr. Yamamoto sighed heavily. "I'm not sure. It's possible that the high density of magic particles could cause some kind of instability or even a dangerous reaction in the future. But for now, it seems to be stable, so we'll just have to keep an eye on it."

Jinpei looked down at the floor, his mind racing with worry and fear. He knew that he had always been different, but he never imagined that it could be something as potentially dangerous as this. He could only hope that they would find a solution before it was too late.

While Jinpei was getting his additional tests, Kosu was waiting for him in the waiting room. He couldn't help but worry about Jinpei. When Jinpei finally returned, Kosu noticed that he looked worried.

"What's wrong?" Kosu asked, putting a comforting hand on Jinpei's shoulder.

Jinpei hesitated before telling Kosu about his high magic particle density level. Kosu listened carefully, and then put his hand on Jinpei's forehead. "Don't worry, Jinpei. I'll help you figure this out."
