Hara Misuzu works as a high school teacher and prefers to keep a distance from her students. In the past, she was raped by her best friend’s boyfriend, Hayafuji, after he found out she liked him. She didn't report the crime to the police, and she didn't tell anyone else what had happened. She still suffers from the trauma of what happened, but she continues to have a forceful relationship with Hayafuji, who is now her best friend’s fiancee. Adapted from the manga series "Sensei no Shiroi Uso" (先生の白い嘘) by Akane Torikai (鳥飼茜).
