Mysterious Adventure

Akira runs into Aika who, having just been dumped by her boyfriend, reveals how she knew of Akira's feelings for her when he lies about not having a girlfriend. Aika gives Akira the opportunity to try some of her drool, but he backs out realising it could damage his bond with Mikoto, bringing to light that he does have a girlfriend. The next day, Aika decides to approach Mikoto, inviting her to her school's culture festival on Sunday with the news that Akira might be there. Later that night, Aika calls out Akira with a fake wound on her face, manipulating Akira into coming to the festival with her and pretending to be her boyfriend. Akira tries to come up with an alibi in front of Mikoto, but she soon learns the truth from Ayuko. As Akira goes to the festival on Sunday, Aika shows up wearing her old middle school uniform.
