Kou goes out to the arcade with Naoya and his friends. He accidentally spots her coming out of the girl's bathroom, leading him to become surprised at the realization, while she runs away embarrassed. Naoya goes to Hirotaka and Narumi for advice when Kou stops showing up to school. After some attempts at the two apologizing to each other, and having fun working together to evade an enemy, they reconcile.

Another Day, Naoya receives tickets to the movies, and with encouragement from his friend, invites Kou out who, with help from Narumi, arrives in more girl-y clothes, to Naoya's surprise. After their date, Kou admits to how much better she feels whenever she's around Naoya, saying she likes him and wants to stay friends forever; Naoya's slightly caught off guard but still happily accepts. As they head their separate ways, the two reflect on their feelings on what they want in their relationship.
