Kotori meets Kōhei's friend from high school, Yūsuke Yagi, who occasionally looks after Tsumugi. Hearing that Tsumugi seems to hold herself back from eating doughnuts, Kotori decides doughnuts will be their next cooking venture. While waiting for the dough to rise, Kōhei and Tsumugi spend time together and Kotori bonds with Kōhei. The first batch ends up failing due to the oil being too hot, but they manage to get things right with the second batch and produce delicious doughnuts.
