Im so happy to find someone who points out on this overdone cliche, its so annoying and changes my impression on the relationship on this specific part of their character to become bored
Im not hating it cuz I think its useless, I'm hating it cuz its just too much at this point. No matter if its a good or great story, connecting them to their childhood makes me go from :) to :/

what is up with koreans and their obsession with making the characters connected since childhood? this also happens a lot in kdramas, it’s so overused and doesn’t always add anything to the story
