It's finally the day of the Cultural Festival and everyone prepares for their respective groups. Shun's class are doing a "cafe with a twist" and Kaname's class are doing a "stereotypical haunted house". In Masaki's class, they are going to play Cinderella on stage. Even if her role is a mouse, she is desperate to practice her dialogue. The gang watches her performance however, some of them are still wearing their costumes, which made Masaki to notice them easily, got nervous and accidentally mixed her lines up. Chizuru goes to comfort her after her performance.
ついに迎えた文化祭当日。
クラスの出し物で、お化けに扮する要たちや、メルヘンな衣装を身にまとう悠太たち。一方、茉咲は舞台で「シンデレラ」のネズミ役を演じることになり、セリフを必死に練習していた。
春にいいところを見せようと張り切ったものの、見てくれている！と思えば思うほど緊張してしまい、本番で失敗をしてしまう。
落ち込む茉咲を元気づけたのは……。
