However the villainess is watching the whole time as the MC tries her best so that the villainess is finally loved and has a happy ending. The villainess loves the MC as a sister, especially since she grew up with no love from her parents. Even though the MC had made everyone fall for her, once the original heroine, who is also reincarnated, uses love potions to make everyone betray the MC and the annulment from the original story still happens. Once it happened the MC was in despair since shes very kind hearted, but the villainess finally wake up and takes over her body again. The villainess plans to take revenge for the MC. She takes over her grandfather's old land and has a demon merchant move in. That demon merchant was also the one selling the love potion so MC wanted to take that away from the bitch protag. A few other demon children also stay in the land. Apparently the demons in the demon world have been going frenzy, meaning they have no control of themselves until they eat someone. Some of the children demons were sent to the human world but got abused until villainess came to save them. MC2 has gone around becoming even stronger and eventually killing some gods, including one that was the reason behind demons going into frenzy. She is now working on developing the relationship between humans and demons while planning out her revenge.
