Memo.

Mayuko Motohashi is a high-school student in Tokyo. She suffers from an obsessive-compulsive disorder, obsessively writing down everything that crosses her mind. The anxiety happens so often, that she has to buy large amounts of note pads every few days at a stationer. Mayuko’s life mostly consists of two things. Going to school and seeing her female counselor. One day, after a long period of time, Junpei who is the brother of Mayuko’s father reappears, surprising the family. By a coincidence, Junpei also suffers from an obsessive-compulsive disorder, making him and Mayuko begin to share a strange relationship, both of them fighting to overcome their disorders. But one day, Junpei didn’t seem like himself.
