Love Jinx
Plot is good, I enjoyed the manhwa. The love interest will not be everyones cup of tea tho. He's a possessive psychopath(?) with quiet homicidal tendencies. Not that he actually killed someone (I think at least). Is the relationship toxic? Yes, I would say it is. Currently it seems that the ML tries to isolate the protagonist because he thinks everyone is into him... We'll see. (Edit: In later chapters I like Woojin more...) There's no second love interest but a few past lovers of the protagonist. And then there's a little subplot about three guys but not a lot about them so far. And not gonna lie, I kinda like the brother. (Am I the only one who doesn't really care much about Kihoon?) If you're okay with that kind of ML you should enjoy this one
