heeseung was your sworn enemy, atleast that's what you thought. this so called rivalry started at the ripe age of seven when heeseung accidentally ripped out your poor barbie's head.

ever since then both of you ( actually, just you ) have been doing anything to get on each others nerves. like how you once tried ruining his shirt by leaving lipstick marks on them, thinking he would get annoyed and would never wear it but instead he wore it happily to class the next day, proudly showing it off, only adding to your embarrassment.

but you never noticed that beneath this rivalry, was the lee heeseung who harboured feelings for you that were something more than just rivals.

one day, while yapping about how you want your future boyfriend to treat you to your bestfriend in the cafeteria, you failed to notice heeseung who was standing nearby, listening to your conversation and making a list of everything so that he's a perfect candidate to be your ** future boyfriend.

one day while presenting in class, you lost your favourite necklace and spent days searching for it, only to never find it again. little did you know that heeseung had found it and kept it with him as a lucky charm for his football matches.

you only noticed it when you were forced to attend a football match by your bestfriend, chaewon, as her boyfriend was playing. you noticed the similar necklace being wrapped around his wrist. when the match was over, with heeseung's teams victory, you immediately went to confront him.
