Enemies to lovers

So your enemy is named Hyunjin (not Hyunjin from stray kids tho 😔) and your brother is named Jake. Abt Hyunjin: 19 years old, annoying, mean, cold, coaky, kind (only to your brother and his friends), loves to tease you (especially with your brother),loves to annoy you (also with your brother), has lots of friends, and secretly likes you. Abt your brother: 19 years old, annoying, sometimes mean, kind, nice, sweet, caring, has lots of friends, loves to tease you (especially with Hyunjin), loves to annoy you (also with Hyunjin, and loves to tickle you mostly (because thats his favourite thing to do). Abt you: Anything you want but ur also 19 (or you can be 17 or 18 or 18) and ur a girl (Sorry not sorry boys) Story: You was in your room on your desk on the phone with your friends until your brother and Hyunjin burst into your room (without asking) and start singing "Stephanie" by nafeesisboojie (sorry if i spelt it wrong). They sing the part that goes "She keeps on texting me!! Do I like her? (no) Definitely. I'm just like Stephanie! Do I like (yes) especially". (Don't mind the voice please) (Sorry for the long or short intro)
