The manga's main premise is about a boy discovering that a girl in his school had been sexually abused by her stepfather. There is heavy exploration of themes of child sexual abuse, teenage pregnancy, abortion, and the effects of this on one's physical body and mental state. There is also an attempted rape from a man who is not her step father, but the boy saves her. The manga's handle of the topic matter is done respectfully with showing symptoms of abuse that are not usually explored and her not be sexualized by the boy or the narrative.
