Trigger warning: r*pe, alcohol and possible drugging.
A goes to B, their mortal enemies' house one night, clearly drunk and possibly drugged. He's shaking and scared, genuinely crying which B had never seen before. It's obvious what had happened, even without asking. Surprisingly, B immediately ushers A inside and tries to help.
It could be a scenerio of A refusing sex with a boyfriend when drunk, or it could be A going to a bar.
It doesn't matter who's the hero or villain but I would prefer to be A please
