i'll answer this myself, around chapter 40 and so on he becomes less annoying. i actually have taken quite a liking on him lol he's cute in a way and i love his moments with yunshin. i can tell his feelings are genuine. and the playful banter between him and yunshin? to die for
he's insufferable as fuck. i don't get what his problem is but as of now i'm giving him the benefit of the doubt
