Madarame-sensei no Mousou Gakkyuu Nisshi

A teacher with an unusual personality experiences internal conflict when faced with difficult choices, as her mind divides into three distinct personas: a leader, a maiden, and a slob. After a breakup with her boyfriend, she acts recklessly, cutting her hair and getting into a fight, which leaves her injured and discarded in a pile of trash. A student named Sena helps her by arriving on a white bicycle and tending to her wounds. Madarame begins to develop an irrational infatuation with Sena, questioning whether he is a savior or if her feelings are unfounded.
