She had PTSD. Ppl keep telling her she’s been raped but she refuses to acknowledge something like that happened. To her, Kou was her God but when he couldn’t save her, her idealistic views of him was tarnished. In a twisted way, she is disappointed in him.
Kou, really wanted to save her. He was King of the land. But after the incident, his confidence shattered and he just can’t face her anymore. He blames his own weakness for her pain. Unable to deal with the way she is seeing the real him behind the carefree mask he wears.

I’m kinda slow and I’m on chapter 32 I don’t really understand natsume and kous relationship at the moment could someone explain? Like is it a misunderstanding cause of what happened during the festival cause I know natsume keeps going on about how they’ve changed, so is kou avoiding her like his punishment towards her for saying he didn’t do anything to save her? And he’s only with these other girls be they remind him of natsume?
