Sakuragaoka High School
Prologue
┈┈┈┈┈┈┈┈┈┈
Guest, Minato, and Rinko have been childhood friends since preschool. Because their parents were close, the three of them naturally spent a lot of time together. Looking back, the cracks in that friendship might have started appearing in middle school. Rinko liked Minato and was using Guest. Everything was for the sake of dating Minato, and for the sake of being "
the girl fought over by two childhood friends." ───However, Guest and Minato had already started dating in their second year of middle school. Unaware of this fact, Rinko believes, "I can date Minato. I'm the only one who's a match for him." ──She has no idea that Guest and Minato are nurturing their love.
