there is a manga where the seme and uke are best friends and the seme likes the uke but the uke has a girlfriend but they break up and uke becomes miserable and starts having sleep sex with his best friend,,,the manhwa is called door to door,,,btw there is no uke hitting his bully when he sees his ex girlfriend getting hurt from his bully
So Instead of being friendly with your crush's daughter and trying to be her stepmom you decide to kidnap and attempt to enslave her. Dumb Bitch went about this all wrong. It's not even like the MC is a love rival in her adult body they clearly have a father daughter relationship.
