Yuuto's life becomes a minefield the moment a third girl enters the equation, turning his secret-keeping into actual emotional labor. The show knows the difference between harem comedy and watching someone actively choose kindness over convenience, scene after scene. It's a love triangle that refuses to punish Haruka for being a otaku, or to make her secret the punchline instead of the point.

Yuuto guards a major secret: his friend Haruka, a respected and well-off high school girl, is a devoted anime and manga fan. When another girl in their circle starts developing feelings for Yuuto, a romantic rivalry breaks out among the group, and Haruka finds it harder and harder to cope with the attention he gets from other girls at school. Meanwhile, Yuuto keeps helping Haruka enjoy what she loves most: drawing manga, watching anime, and going to special anime events. The show is a lighthearted romantic comedy with ecchi touches, finding humor in the rivalry, the secret hobby and the growing bond between Yuuto and Haruka.
