Touch Blue

Junya keeps a handkerchief from Kyouichi, a memento from their past encounter. They reunite as step-brothers after their parents marry. Junya wants to return the handkerchief but doubts Kyouichi remembers him or that night. He also experiences sudden, unexplained pains and has no one to reach out to except Kyouichi. It raises the question of whether the pain is genuine or a reason to be close to his step-brother.
