Saying that you can't just change their personalities is a very bad generalization, as people become influenced by their surroundings, i.e., other people all the time. Although it could be true that they initially were possessive or clingy, the Uke seems to have GREATLY intensified these traits within them.
Either way, they hella crazy.
I don't understand why people are saying that the mc turned hyung and mister sugar daddy into psychos. I mean just because you break up with somebody in a bad way that person does not have to become insanely obsessed with you and forget completely about morals and normal behavior. Also, you can't just change their personalities, so that means they initially were possessive and clingy individuals.
