Honestly, regardless of the trauma the MC has to suffer, Ayame is a nice enough girl that it shouldn't matter at all. She gives him her affection and actively confess her love, and even when he rejects it because of his trauma, she even wants to work hard to become his ideal girl. C'mon dude, she's not gonna stand you up after all that, try to make an effort to get over it or else it'd just be rude to the Ayame who's trying her very best.
