most people say mutsuki raped haise's body in chapter 114, but that's just not true. the scene is disturbing and uncomfortable, yes, but it's not rape. nothing sexual actually happens beyond mutsuki being topless and pressing his chest against uta (who was disguised as haise). it's important to look at what’s really going on with mutsuki's trauma and mental state.
mutsuki was abused growing up physically, emotionally, and sexually. he was never taught what real love or affection looks like. so when haise showed him any kindness, he latched onto it and convinced himself haise loved him romantically. that's why he misinterpreted things like haise accidentally walking in on him naked. in mutsuki's mind, that meant haise wanted him too.
when haise left, mutsuki felt betrayed not just as a friend or teammate, but as someone he thought he was in love with. he spiraled. he thought haise had "abandoned" him, just like everyone else who had ever used him or claimed to love him.
so in chapter 114, when he attacks uta (thinking it's haise), he's not trying to rape him. he's trying to prove he's desirable. he takes off his shirt, arches his chest, because that's what every other man in his life wanted from him. he thinks that's how you get someone back. he doesn't touch uta in a sexual way, only hugs the body and confesses he loves him. it's messed up, but it's not rape.
this scene is about mutsuki's warped idea of love, his gender trauma, and how his past abuse twisted his sense of intimacy. it's tragic. it's meant to be disturbing. but people need to stop saying "he raped haise" because that's not what happened.
