School years should be the best time of our lives, but Lune spends his days invisible, no one taking an interest in him. At the start of a new summer, however, secrets are about to overturn his ordinary life.
A secret love story begins the night before summer holidays when high school nobody Lune gets together with school princess Star. It has to stay secret because school prince White, the one who invited Lune into their friend group where he got to know Star, also likes her. The events of that summer night become the starting point of a chaotic story of friendship, love, and hate.
