so it was all that black haired b-tch fault, uh? she was like "how dare him not want his little sister marry a creep? he needs to leave and then tell said that little sister he died, that going to solve everything" what's that? everything blew up in your face? well cry me a river.
I do feel bad for him and the little sister (well now that she's a yandere, not so much) they were collateral (kind of)

Who the hell is this black haired woman ?? I thought she just servant or caretaker

Who the hell she is to tell someone in the family to leave.. I would just kick her out of the house if she speak like that

Put that seawitch in her place.

ok
