I think this was very unique story but i think the "second ML" , 'Love triangle' is really unnecessary. Yes, its messed up. Mc and MLs relationship was really spooky and weird in a interesting way??idk. They are both messed up, and i prefer ML over red hair guy. But mc killed ML and ended up with red hair guy. "But we need a character mc wants tobgo", that character could be a friend or family. It didnt have to be love interest. That mc is jumping one relationship to another and mc isnt even happy in the end. Idk man, i really liked black hair guy. It was very unique way to explore this type of story so everything related red hair dude and ending kinda ruined it for me. Its just my opinion But it is what it is.
