I read a novel like this too called Love You to Death. I forget who wrote it but it was SUPER good. It ended up that her best friend was the killer that was suffering from a psychotic break. I really like these kinds of stories. Though I don't think that this one can go the whole split personality route when we've seen the culprit looking at her and stuff.

i’ve read this story in wattpad named psycho’s love interest and this webtoon kinda has the same storyline with the story
in the story it turned out that the mc is also the one responsible for the killings related to her and she has multiple personality disorder and i think this webtoon will also follow the same route
