It's Tadano's first day of high school and all he wants to do is blend into the background. He starts to get to know Komi, a quiet girl in his class.

During the school health checkup, competitive classmate Yadano is determined to clock better results than Komi, whom she sees as her ultimate rival.

Komi wonders why everyone starts staring at her when, like the rest of the student body, she switches from her winter to her summer school uniform.

The students of class 1-1 have to decide what they're going to do for the culture festival — a task they're all taking way too seriously.

At the culture festival, Najimi is up to something. They try to rope Komi and Tadano into their scheme.
