Otome, Minami Obuchi and Natsumi Koizumi are together when they see Makoto and they both pressure Otome into asking Makoto to see the festival. However Makoto asks to talk to Otome first and due to very poor choice of words Otome is led to believe Makoto has already slept with Koizumi and now wants it's Obuchi's turn even though she's bad. Makoto finally uses says they skipped their shift and explains Kotonoha's been sitting at the reception all this time the misunderstanding is cleared up. Kotonoha and Makoto leave to see the festival and Makoto explains his relationship with Otome.

Makoto suggests going to his class' store to eat when Nanami and Setsuna conspire to break them up for Sekai. They then lie to Makoto saying they're short on people. After some begging Makoto decides to help. Makoto only starts helping a little while when Setsuna tells him they're okay. Makoto goes back to find Kotonoha gone, Nanami having chased her away.

Makoto goes to the reception and finds Kotonoha. She offers to go to the break room, but Makoto refuses saying he can't go on like this. At the bonfire, Taisuke tries asking Sekai to dance with him, but she refuses. Then, Makoto shows up and dances with Sekai. Afterwards, Sekai asks him if he knows the meaning behind the folk dance, but when she realizes he doesn't, she quickly changes the subject. Then she asks if she can stay by his side, even if it's just as a substitute for Kotonoha. Makoto accepts this.
