Ep. 21: Yui's accidental haircut and the girls' decision to attend the same university together.

21

As graduation yearbook photos approach, Yui uses Ui as a model for hairstyles but feels strange wearing her hairpin. Although the seniors have completed club activities, the group utilizes the light music club room to study for entrance exams, despite Yui and Ritsu still undecided on their university choices. During the photo session, Yui sneezes while trimming her bangs and accidentally cuts them short, resulting in a new appearance. After the pictures are taken, the girls discover that Mio declined a university recommendation to remain with her friends. Inspired by this, Yui, Ritsu, and Mio submit their preference applications to Sawako, choosing to enroll at the same women's university as Tsumugi.
