Futoshi Mishima is a high school boy living in an isolated rural town in the Heisei era. Ostracized and bullied by his classmates for having long hair, he never resists. His only solace is secretly wearing his mother’s lipstick and styling his long hair in waves—becoming the "cute" version of himself. One day, bullies cut off his precious hair with scissors. Shocked and devastated, he returns home. But when he sees himself in the mirror… “Whoa... I’m... cute.”

Futoshi is nearly forced into a car by a group of men—only to be rescued by Makoto Kirino, the leader of the very group that bullies him. Though grateful, Futoshi's thanks enrages Kirino when he notices Futoshi is wearing lipstick. Later, on the school rooftop, Futoshi sees Kirino applying the same lipstick to his lips. “A shared kiss? Could it be that Kirino… actually likes me?” A surprising side of Kirino is revealed.

Now aware of Kirino’s true colors, Futoshi spends his days secretly meeting him on the rooftop, sharing love stories and trying makeup. One day, the most popular girl in class, Rinka Fujii (Hiyori Kata), confesses her feelings to Futoshi after school. As he hesitates, Kirino’s words echo in his mind… Futoshi’s first experience dating a girl could change everything.

Unable to go all the way with Rinka, Futoshi questions his identity even more. Kirino continues to comfort him during their rooftop meetings. “Someday, I hope I can say out loud, ‘This is who I really am.’” Meanwhile, gossip about Futoshi's appearance spreads among the town’s housewives. The reason Kirino hides his true self and the past of social studies teacher Mr. Yanagida (Aran Abe), who keeps a close eye on Futoshi, slowly come to light.

Mr. Yanagida finally reveals his true colors during a cruel “punishment game” targeting Futoshi. Even Taro Yumeno (Kota Fujimoto), who used to tease Futoshi, begins to worry about him. Kirino, sensing something sinister about Yanagida, tries to warn Futoshi—just as Yanagida’s dangerous intentions start closing in. “No way!” Will Kirino and Yumeno arrive in time to save Futoshi?
