notes about marie, you might already guess who she is. as for her back story.
Marie is indeed leon`s little sister in her previous live. she likes to get spoiled and complain. and her brother always puts up with it. he was always the one cleaning her mess up. you might also guessed it but leon likes to play the bad guy. but is kind at heart/does the right thing when it matters. so what happened when he died in pre life.
their parents found the messages between the sister and him. she has always been stealing both their money, spending on luxury and vacations. and her brother is no longer their to clean her mess up. and the parents disowned her for indirectly killing her brother. and all the other shit. she has been homeless and then a prostitute before eventually dying. blaming all that on her brother. and now karma.
she is reborn in a poor household in debt, with idiotic parents and siblings. everything is getting pushed on to her. and later also throws her name around putting all the blame on her.
Sevens sister was possesed by an evil spirit. She wasnt even there by fhe time they fought.The author truly must have had bad experiences with sisters in his real life. Almost every novel of his has a sister that pretty despicable
