It's nice that one of these actually has the abusive friend go "Damn, I was an annoying piece of shit. While I do still love MC, maybe I SHOULDN'T try to get back with them, for their sake."
Too me a minute to remember the details. Kind of glad the bitchy ojou-san sword girl is trying to be a better person. No idea who might be in that hole, though.
Guy got sick of being abused by his childhood friend. Left her, discovered he was good at magic instead of swords. She got sad looking for him until asshole noble attempted to force her to marry him. She ran away hoping to find MC to apologize.
