I'm so sorry y'all but .... I love yandere (possessive guys) in general but this one takes the cake for me cuz he cares about what she thinks of him. And imo she knows that he is manipulative af to get what he wants, she noticed it from the beginning (he watched her beg for help and later apologized later But still he was making her dependant on him) and she had no choice but to stick to him. However in the recent chapters she could have just escaped with kotaro yet she indulged with whatever he was planning and even apologized for him, she absolutely knows and IS IN LOVE and gives no fuck !!! As she should tbh !! I support her. The relationship doesn't seem out of balance, to me at least
