When Kōhei's class competes with another class doing a crêpe stand at the upcoming cultural festival, the students turn to Kotori for menu ideas. Tsumugi becomes downhearted when her classmate Hana calls her weird for wanting to play a mascot character in a class play. As the gang gets together to make sweet potato crêpes, Tsumugi is comforted in knowing that Kōhei is always thinking about her. Kōhei makes Tsumugi a costume for her play, encouraging her to help Hana understand her more. Tsumugi manages to befriend Hana and perform in the play happily while Kotori's sweet potato crêpes become a huge hit at the festival.
