Haruka feels betrayed by Nayu's announcement and stops being friends with her. That same night, Mizuno's apartment catches fire. These events leave everyone in a negative mood, and Nayu's texts to Haruka fall upon deaf ears. Later on, the girls help Nayu with her move, but Haruka doesn't show. After Yako pleas with her to make her final goodbye, Haruka finally meets up with Nayu the next day and the two finally apologise. Haruka, Yako and Hiroki see off Nayu as she heads to Kyoto, whilst they keep up the Underwear Society. However, Nayu later comes back after Keigo and Mizuno make arrangements for her to stay at school.
