set in the 2000's, heeseung was your best friend and the epitome of a teenage dirtbag while you were the opposite. he had bad grades and rebelled against his parents often while you were popular with a pretty face and sweet personality. no one knew why you guys were close, but you just were. he considered himself 'unlovable' while you loved him like it was breathing. today, he was rotting in his room while you were oblivious to his bad mood.
