Yuyushiki: Komarasetari, Komarasaretari

Yuzuko and Yukari are as committed as ever to teasing Yui, until their latest round of pestering sends the three into a discussion about why people enjoy giving one another a hard time. Their wandering curiosity soon turns another ordinary day in the Data Processing Club into a chain of jokes and unlikely research topics.

Chiho later shares how her friendships with Kei and Fumi began, while the girls start thinking ahead to their third year of high school. Even with change waiting in the future, their relaxed conversations make it clear that some parts of their friendship are unlikely to change at all.
