Story

Late at night, while working part-time at a convenience store, college student Yamamoto reunites with his former high school classmate, Megumi Hayashi. Back in school, she was known as the class’s most beautiful girl, yet also a proud and arrogant “queen.” Though the two didn’t get along in high school, Yamamoto discovers bruises on her wrist and, intending it to be just for one night, shelters her from her abusive boyfriend. Before he realizes it, however, a strange cohabitation begins. Confused by the situation, the two gradually come to see sides of each other they never knew before.
