genderswap yoonjin au where top scholar hyejin has had a crush on basketball shooting guard yoonji (because basketball player yoonji concept is CUTE.) ever since they had gone to the same junior high.
everyone in class thinks yoonji is very very intimidating so they never approach her except her close friend hoseok who knows about her throughout (he is gay for jimin uwu)
yoonji is actually a big softie and hyejin is aware of how soft yoonji is but refuses to approach her about it
one day while walking home hyejin sees yoonji hanging out with hoseok, yoonji hugging someone in a kumamon costume with the biggest gummy smile and hyejin can't help but to flush and feel her heart explode from how cute it is! ))):
yoonji is so happy and smiley she doesn't even notice how hyejin is staring at her with loving eyes but hoseok surely does, so he catches hyejin the next day in her free time and asks for her to hang out with yoonji for the next few weeks, not expecting for hyejin to take the offer with no hesitation.
hoseok was going out of seoul for a few weeks and needed someone to keep yoonji company now he was gone, and now hyejin has the chance, not knowing it would mean taking care of her for 14 hours per day but happily takes on the offer ))):
