the brother's best friend trope | lee heeseung

one

being park sunghoon's little sister was difficult.

it was difficult already to have an older brother that annoys you every five seconds, but it was even more difficult because he just had to have hot friends.

hot friends that sunghoon made sure knew that you were completely off-limits.

when sunghoon entered high school, he was immediately somehow made popular and quickly made a small friend group with the other popular boys in his grade; jay park and jake shim. another boy, who was a year older than sunghoon also hung out with them quite frequently; lee heeseung.

though you were only a year younger than sunghoon, he treated you like you were five years old. your friends thought that it was sweet that sunghoon was so protective of you- but you thought the complete opposite about it. since he treated you like a baby- that meant his friends treated you like a baby.

sunghoon's friends knew that if he ever caught them even glancing at you for more than a mere second, they would get reprimanded by sunghoon in an instant. sometimes they even thought that sunghoon was a little too protective of you, but then again sunghoon knows how his friends think and how they treat girls. he doesn't want you to get heartbroken like the thousand other girls they have played.

the first time you ever saw lee heeseung was when you were just starting year 8 at your school. sunghoon had brought home heeseung one day after school so they could play some video games together. heeseung was in year 10 at the time, and he was just starting to grow into his features. that didn't stop you from almost physically drooling over him when he first stepped foot into your kitchen.

you remember your mother introducing herself to heeseung, smiling at him and welcoming them into your home, but what she said exactly is all a blur because you were so in shock about how and why this hot guy was friends with your brother.

"that's y/n, but you don't have to talk to her she's pretty annoying." sunghoon's voice got you out of your drooling session. sunghoon pointed his thumb over his shoulder at you before going into the fridge to get him and heeseung a drink before they head up to his room.

"hi, y/n." heeseung said softly with a smile as he stood at the table beside you, waiting for your brother.

"hi." you forced yourself to say, surprising yourself when it came out in a normal tone.

"okay, my room's this way, i'll show you my games and we can play whatever one you want." sunghoon shrugged, leading heeseung up the stairs. "oh and y/n," sunghoon stopped and called to you from the middle of the staircase, making heeseung turn back around to look at you, "don't bug us, seriously, i mean it."

"wha- i won't!" your jaw dropped out of embarrassment and ridicule, "why would i wanna go into your musty room anyways." you rolled your eyes, turning your body away so they wouldn't see the flash of pink on your cheeks from the humiliation.

"shut up, it is not musty." sunghoon grumbled, turning again to head upstairs, you heard a soft chuckle from heeseung as he also turned around and followed your brother up the stairs.

after that day, you saw heeseung at your house a couple of times per month, along with jay and jake. they quickly turned into regular guests at your house, walking into your residence without even knocking by the end of the school year. your parents had started acting like they had just randomly gained three extra sons.

at first, whenever you were around jay or jake, you could sense that they were a bit reluctant to talk to you. you figured that it was just because you were younger than them. there would be times when jay and you would be cracking jokes in the living room whilst he waited for your brother to finish getting ready, and as soon as he heard sunghoon come down the stairs, jay would back away from you and act as if he didn't know anything about you.

jake didn't really care if sunghoon saw him smile at you, or even just acknowledge your presence. though, you could tell sunghoon got a bit annoyed when he saw jake interacting with you. still, jake would never be caught dead being alone in a room with you, just in case, sunghoon decided to end their friendship then and there because of it.

heeseung, on the other hand, the one that was the most introverted out of all of them, did not care about sunghoon's stupid over-protectiveness of you. heeseung always made sure to say hi to you, to open the door for you when you all started walking to high school together. he didn't care about what sunghoon said or thought because heeseung knew how much sunghoon trusted and adored him. sure, it was annoying seeing his best friend talking to his little sister, but not as annoying as seeing jay or jake talk to her.
