Stylish high school student Poem Kohinata enjoys expressing herself by dying her hair blond and wearing short skirts to school. Her appearance often gets her in trouble with the dedicated but strict class monitor, Tougo Sakuradaimon, who sees Poem's attire as a violation of the school rules. While taking supplemental lessons, Poem is surprised to discover Sakuradaimon—despite his dedication as a class monitor—is also taking part due to a severe lack of academic prowess.

However, the lessons spark a change in their relationship: Poem and Sakuradaimon both admit they have misjudged each other, bringing the two closer. Their exchanges become the daily norm, and Poem struggles to contain her emotions as Sakuradaimon expresses sincere affection for her. With her friends and other eccentric committee representatives thrown into the mix, the two begin to enjoy their school days more, even as they continue bickering about the rules.
