Mitsuki, and Yūya are invited to a fitness pool center by Ayaka. Once there she runs into Yukina, also present are Shōtarō and Moa. Mitsuki who is wearing a bathing suit refuses to go into the water out of embarrassment that her belt might be seen. While watching everyone have fun, Neko introduces herself to Mitsuki and tells her she accompanied them there as her father owns the place. She also tells that her father wanted more opinions from people and allowed them to stay for free if they complied. Mitsuki thinks of Yūya while watching him have fun and reacts after seeing how his friend Shōtarō is with his sister Moa. Yūya accidentally hits his head against Yukina's causing him to fall in. Upon seeing this Mitsuki jumps in to help him but it is not needed as he turns out to be okay. Mitsuki's leg cramps up however, and Yūya carries her out and away someplace to sit. Unknowingly to both of them Mitsuki's bathing suit had fallen off. Yūya puts her down and is shocked to discover her wearing the belt, to make things worse some people come along to walk by. Yūya apologizes to Misuki and then proceeds to kiss her hiding the belt from view and making the people walking by think they are a couple making out. Yūya then takes his swimsuit off causing Mitsuki to scream in embarrassment and the heart on the belt to fill up more. It is shown afterwards that Yūya gave her his swimsuit that he wore two pairs of swimwear for some reason. The next day, Yūya thinks of why Mitsuki could be wearing the belt, while unconsciously rubbing Mitsuki's panties on his face that had been given back to him. Mitsuki meanwhile who stayed home from school sick, hits her breaking point and is ready to cut off the belt with scissors when she collapses. Hiyori seeing that the belt on her is not looking good possesses Mitsuki. She then goes on top of Yūya when he comes to check to see if Mitsuki is alright after getting home from school. As Hiyori asks Yūya to do her she comes out of Mitsuki and reveals herself to him, in response he confusingly asks who she is. (Source: Wikipedia)
