@KinokoTvT no ones justifying anything,joo jaekyung had a very messed up and abusive childhood while Kim Dan had a loving grandma tho things were still messed up, Ik it doesn't justify his behaviour or anything but raised in a place like that with no therapy or a loving environment I think he just has anger,hate and pain to give out just the way he was given. He's a good guy he just doesn't know how to express it anyway I think Kim Dan is a wimp ( sorry not sorry 🫣)
Everything has it's purpose
