Volume 1: The primary romance is between a high school student and a college student. They are about two years apart in age; she is mentioned to have just finished 11th grade, while he just finished his first year of university. Their exact ages are never specified. They kiss once during the book but otherwise have no sexual contact. The main character's boyfriend attempts to rape her before she fights him off and escapes. Volume 2: No rape or sexual assault. Volume 3: A man flashes a crowd. This is played for laughs. The main character runs into an ex-boyfriend who previously attempted to rape her. This causes her to have a brief flashback to the incident and she is too scared to move or speak until her new boyfriend arrives and comforts her. The ex is portrayed as having become a better person since their breakup, but it is clear the main character will have no further contact with him if possible.
