the brother's best friend trope | lee heeseung

twenty

as the final weekend of sunghoon living with you before he went to university came, it was almost tradition that he throws a party in honor of going away. your town's infamous party boy and his friends would be leaving to party somewhere else. what would your town do without them?

almost everyone in sunghoon's grade and your own was filling in your house. it was the biggest party that they've ever thrown in all four years of high school. even the '01 liners that graduated last year had come to see heeseung and send sunghoon off for university.

unlike last year's going away party, you were actually allowed to come to this once thanks to sunghoon's less strict protectiveness of you.

of course, heeseung and you couldn't be seen beside each other, but you were both planning on telling sunghoon the big news tomorrow. you both weren't sure of how he would react. hopefully, he'd be happy though since he and heeseung have already put a down payment on the apartment that they're going to be sharing for the year.

as midnight approached, a loud clinking sound captured everyone's attention and the loud music turned off.

"excuse me everyone!" a loud voice boomed, getting everyone to be quiet. there stood hwang intak on your coffee table in the living room. you haven't heard from intak since the beginning of the summer, you figured that he was just busy or that he found a new friendgroup to hang around with. he was holding a fork up to a beer bottle, "as i'm sure everyone is so sad to see the '02's leave this year, i have some happy news that i'm sure. everyone would love to hear!" intak started, everyone in your house nodded and made sounds of agreement, "i'm sure the one and only park sunghoon will love to hear this one especially,"

you stopped smiling at the mention of your brother's name, glancing at him and then heeseung from across the room. heeseung was looking uncertain as well.

"it has been brought to my attention, that park y/n is fucking her brother's best friend!" intak smiled, a gasp going through the room and your blood ran cold as you made eye contact with your very furious brother from across the room. "isn't that right, heeseung?" everyone in the room turned and looked at heeseung who was standing right beside sunghoon like he normally does. heeseung immediately put his hands up in defense as your brother pushed his chest against his, a betrayed look on his face. you couldn't hear what exactly was being said from all the whispering going around you, but it ended up with sunghoon pushing heeseung onto the chair behind him and then pushing everyone else out of the way to storm up to his room.

"okay! i think that's about it for tonight. everyone has a good school year and get the fuck out!" jay stood up on your coffee table now, pushing intak out of the way.

a pleased-looking intak came up to you right after.

"intak, why would you do that?" you asked him, tears welling up in your eyes from humiliation and fear of what's going to happen to you and heeseung and your brother.

"you know i've liked you since the day i met you park y/n. and what do you do? you turn me down, treat me like just a friend in front of everyone and then go and use me at some party- never to speak to me again?" intak explained to you, you shook your head no, trying to find some words to speak, "no! don't y/n. i thought it was weird when you were suddenly all up on me at the first party of the summer, and i knew you were acting weird all night! i saw you looking at heeseung too! i just never put two and two together until jungwon told me that you've been fucking him behind everyone's back!"

"intak! it's not like that! i'm sorry! what i did was wrong and i'm truly sorry! but you didn't have to go and do that! you just ruined my own relationship with my brother!" you cried out to him, your hands shaking at your sides.
