Yandere

A closet yandere, he can be creepy, very possessive and protective of the MC but just not around her. He says its a bad habit, it seems he'll stop being yandere (he does) for the better and to have a healthy relationship.

Bad guy is a yandere (MC's ex-Lover) and held her captive in his house as he beats her senseless and gives her just enough love so she can only relay on him. She dies but is reincarnated.

The ML seems to have fallen in love and the MC has basically (involuntarily) become the ruler if the house cuz he would probably do whatever for her.
