Imagining the guy you like being NTR gangraped is wild, she might be the most insane yet. At least most of the others were just having delusions of living with him and starting families, damn girl.
Honestly, this should have been the "loser" Aya's scenario. She gets cucked by the others but manages redemption and saves the day. She could really use the win.
Ok that's some insane thought process, to be able to imagine a life in a vast isekai world in just 0.03 seconds. No wonder the other girls call her the brains of her class.
