Seven outcast seventeen-year-olds, four girls and three boys, share their lives and struggles with you, the protagonist, in Studio Kaab's first work, an interactive drama animation. Among them is a girl who is younger than her body makes her look and a boy who would sooner throw punches than shake hands. The title draws on the four-leaf clover, a mutant among ordinary three-leaf plants that is still said to bring luck, and treats these abnormal teens the same way.
