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

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.

Komi decides to write a letter to Najimi to clear up a misunderstanding, but she might be too nervous to give it to them.

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.
