I really want him to basically NTR her and get with someone else because of her attitude. I might be slightly annoyed at the tsundere trope. She won't get with him because she's embarrassed but also prevents him from getting with anyone else. From how she stopped this event from happening it's clear the future she sees is changed by her intervention, so the argument of her thinking he'll be happiest with her doesn't hold up. I'm probably overthinking it though, this isn't meant to be coherent.
