Manga
Yuuki saves Roka from Makoto, but his true identity is exposed. Yuuki decides to be upfront with his actions and leads Kotonoha to the library's storage room, where Makoto and Sekai are making out. To Yuuki's surprise, Kotonoha doesn't seem to be bothered by it at all and Makoto reveals that they are in a three-way relationship and that both girls are okay with sharing him. Yuuki later meets with Kotonoha to explain himself but Kotonoha reacts coldly, believing that Yuuki wanted to steal Makoto away from her by using his Yuu persona and threatens him to stay away from Makoto. Despite being disillusioned by Kotonoha's true colors, Yuuki decides to move on and falls for Roka.
