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.

On the school sports day, Komi isn't sure how to properly cheer for her classmates, but she does her best. Then, it's her turn to run the relay race.

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

White Day is coming up, and Tadano wants to give something to Komi in return for the chocolate she gave him on Valentine's Day.
