I think the whole point is him having borderline personality disorder or smth. They did show his background/story so if you reread it youd maybe understand why hes like that.
that just shows ur a sane person and mokyeon is mentally unwell. Thats the whole point of his character, he’s dramatic impulsive and is carrying his past trauma. It is dramatic bc it’s the end of the world to him.
am i the only one thinking he's being dramatic? like bohoo he doesn't like you anymore get over it. it kinda icks me out
