刻印

Kouya is a brilliant but antisocial medical student who keeps his distance from everyone, including the gentle Rei, who admires him. He has no interest in friendship or connection, preferring isolation and focusing solely on his research. Despite Rei's persistent kindness, Kouya brushes him off, believing people are not worth his time.

Professor Katase, however, is drawn to Kouya's charm and begins to make his move. There are dark rumors about the professor, and soon Kouya finds himself tricked and imprisoned by Katase, who has sinister plans for him. One month after Kouya's disappearance, Rei, the only team member worried about him, comes to his rescue. But when Rei finds Kouya, he discovers that the professor has turned him into a tool for a horrific human experiment, changing everything between them.
