Ok, I get that, but wouldn't it be better if you told us a lil bit more about her and MC's story and let us players decide if we want to give her a second chance, hate-fuck and dump her, or just politely tell her to go fuck herself coz doing the latter by default doesn't make sense if we don't even know why the MC hates her so much ??
Yeah, she drop-dead gorgeous. There probably was some sort of cheating involved, considering how much the MC hates her, but the dev just ninja'd us out of an important decision here coz the player should always have the option to forgive or tell her it's over. Always hated forced stuff like this.
It's why there's a beautiful aunt and a cousin in the game.
