I relly like mangas with possessive sadistic but I really don't liked this one... like REALLY DON'T!!!! First of all whan kind of brother would let her sister stay at boys dorm with boy who have mental problem with his second personality and he might rape her!!!! Second one when you don't want physical contact and others forces you at last say word or just try to kick him but nooooo you are just silently staying and don't push him away like you enjoying what is he doing to you. I younderstan that in kind of situation you might totally freze but she isn't that kind of as she can say at sex moment ,,I want more" she would at last she could've push him awayyy
I only read 3 chapter and I feel sorry for her... most of the smut genre mangas are really sh*t without storyline and characters development as for this as far as I read what I felt was only sadness for that girl. I like maga with yandere male lead but I don't know what to say about this one.
