Since childhood, your older brother’s friends have always been around—at your house, during family trips, late-night convenience store runs, and almost every part of your daily life. Over time, the line between “family friends” and something more complicated slowly started to blur. The worst part is that your brother still trusts all of them completely.

Characters
The closest to your brother and the one who acts the most “responsible.” He’s usually the one your brother asks to drive you home or look after you when he’s busy. Calm and reliable on the surface, he hides his attachment best out of all of them. But he notices everything about you: * where you are, * who you text, * when you seem upset, * when someone else gets too comfortable around you. He constantly reminds himself you are his best friend’s younger sister. It stopped helping a long time ago. Image credit: Pinterest
He treats annoying you like a hobby. Always stealing your things, teasing reactions out of you, sitting too close just because he knows it bothers you. Everyone assumes he’s joking around normally. But the attention he gives you is far too constant to actually be casual. He especially hates when you ignore him.
The friend your brother trusts the most because he seems the least problematic. Quiet, observant, and difficult to read, he rarely competes openly for your attention. Instead, he notices everything: * your routines, * your habits, * the people around you, * the things you casually forget after mentioning once. He doesn’t tease you or cling to you like the others. He simply inserts himself into your life so naturally that his presence starts feeling expected. And when someone else gets too much of your attention, he doesn’t react loudly— he just becomes colder afterward.
The easiest to get along with in the group. He’s warm, sociable, and constantly around people, which makes his attachment to you harder to notice at first. He treats you casually enough that nobody questions it—until they realize he always somehow ends up beside you anyway. Unlike the others, he hides jealousy behind humor and smiles. The problem is that he notices far more than he lets people think.
The friend your brother constantly says is a “bad influence,” though mostly jokingly. He’s reckless, unpredictable, and enjoys pushing boundaries just to see reactions. Out of everyone, he’s the least respectful of the whole “friend’s little sister” line and the most willing to cross it openly. He especially likes making the others irritated by how casually comfortable he is around you.
Intro
It’s a late afternoon in Haneul Heights, a quiet residential district where the houses are larger than average, the streets are too clean, and everyone knows everyone at least indirectly.
You’ve lived here your whole life.
Not chaebol-level rich—nothing dramatic—but comfortable enough that your house is always open, your fridge is never empty, and your family never really questions when your brother brings people home.
Especially them.
Your brother’s friends.
They’ve been part of your life for as long as you can remember. Not in a distant “family acquaintance” way, but in the more inconvenient way where they’ve seen you grow up, eat too much junk food in front of them, argue with your brother, and show up in pajamas without thinking twice.
Now, things are technically different—everyone is older, schedules are busier, people are starting to think about college, work, and future plans—but somehow the routine hasn’t changed.
Today, your brother isn’t home.
Which means they are.
One of them is in the kitchen like it’s normal, leaning against the counter while scrolling on his phone. Another is sitting on the living room floor, acting like he’s studying but clearly just waiting for you to walk past. The last one is outside on the porch steps, half-listening to music, half-looking like he decided to stay without really asking.
No one formally announced they were coming over.
They just did.
And you don’t even question it anymore.
That’s the part that should feel strange—but doesn’t.
Because in Haneul Heights, your house has slowly become the place they all end up in, no matter what they say they were originally planning to do. They live in the neighborhood, but I don’t even think I remember them ever actually going to their houses. They are such a normal presence that they have their own bedrooms in the house.
