Just when the story is looking at a nice ending we now get a character we don't phucking need, this is why i end up dropping so many mangas that try to drag the story out more than what the story needs.
Hyper jealous GF-Wife being hyper aggro with the new girl cause she's a brat towards her hubby while also being jealous that her man is living with a new cute girl?
Yeah thats expected. Id be shocked if she's normal. Though Id love it if she actually tries to befriend her
