A/n - linked to the previous Hansu Seong oneshot. Platonic pairing
You were the exact opposite of your brother, in more ways than one.
The most obvious difference was your personality. You would think it would be your looks, but it was far more obvious in your personalities than anything else.
You were kind, soft spoken, and you made friends wherever you went. People were drawn to you in any situation, and you seemed like sunshine personified.
The main reason you weren't constantly overwhelmed by a sea of people was your brother. His harsh, callous attitude kept people far away, and his glare was enough to make sure that the few braver souls knew to stay away.
That being said, your general appearance is also different to his, namely your aesthetics. He has the whole skater boy look, like someone who doesn't care much for appearances. You on the other hand care very much. You don't wear a ton of makeup, but you dress up whenever the chance arises. You're not particularly girly, but you look very neat all the time, never a hair out of place.

He's about two years older than you, and because of that, he's extremely protective. Your father is partly to blame for that, his protective parental attitude having rubbed off on Taehoon soon after you were born.
Regardless of the reason for his overprotective nature, you look up to your brother - he's your main role model.
And naturally, since you look up to him, you have just as much of an interest in taekwondo as he does - something that he's very proud of. It also acts as a bonding exercise for the two of you, and the highlight of his day is the time he spends teaching you taekwondo in the afternoon after school.
Even though you're just as good as he is at taekwondo, he refuses to let you fight if the situation ever arises. No, your older brother makes sure that you never have to raise a finger to defend yourself - he fights on your behalf, no matter what.
The only downside of how protective he is, is that you're really sheltered, and consequently, you don't have many friends.
Taehoon knew that if he wasn't there, you'd probably have a ton of friends, but it gives him peace of mind to know exactly who you surround yourself with, so he chases away anyone who he thinks might hurt you.
You're pretty good friends with Minji, Manager Kim's daughter, but you don't see her as often as you'd like.
When Taehoon starts making new friends, he tries to keep them away from you for as long as possible. But of course, things rarely go according to plan. They eventually catch wind of the fact that he has a younger sister, and they insist on meeting you. He knows that they're under the impression that you're a mini version of him, and he also knows that they'll be shocked when they realise how nice you are.
Eventually, he caves and agrees to let them meet you, only once you say yes. His only rule is that they aren't allowed to record you - he doesn't want any of your personal life on the internet, especially not your face.
Obviously, they're all shocked when they meet you. Who knew someone as intimidating as Taehoon could have such a lovely younger sister? They're even more shocked when they witness how kind he is to you, treating you far better than he treats any of them.
When Hobin askes why he's so nice to you but so mean to everyone else, he receives a swift kick to the back, followed by Taehoon telling him to "stop asking such stupid questions".
You're whisked away by Gaeul and Rumi who quickly adopt you as their younger sister / best friend. Honestly, they're really the only two Taehoon allows near you for a while - he glares at everyone else whenever they try to approach you.
Boys are definitely off limits until you're old and grey - something he's sure to remind you of as often as he can.
After the fiasco of meeting everyone for the first time, his friends quickly become your friends.

Taehoon makes a habit of taking you out once a week. It's something that both of you look forward to, so he's sure to always make time for it.
He usually takes you out for breakfast or lunch, or to the arcade for a few hours - really whatever you feel like doing. Of course he pays, no matter how much you protest about it being equal and fair.
Spoiling you is something that he does regularly. He buys you snacks and small gifts every few days and brushes off your thanks each time.
The only thing he askes for in return is some time with you - or on the rare occasion - physical affection.
You're the only person he accepts it from, so you're more than happy to smother him in a hug when he askes, because he rarely does.
Any small gift you get him will be immensely treasured and he'd take care of it like his life depended on it.
Taehoon also loves your smile - he always tells you how it brightens his day.
You're the furthest thing from being insecure because he compliments you all the time. If people ever try to point out a flaw or make you feel bad about yourself, he makes sure to tell you that they're wrong. Because of him, you don't really think about how you look, and it's never been a concern.

Taehoon keeps you out of all of his problems.
Mainly because he doesn't want you to worry, but also because he doesn't want you to get involved.
Because you look up to him, you try to do many things the way he does it. You're also fiercely protective of him, and you hate when people badmouth him or try to hurt him.
Obviously he wants to avoid getting you involved, so he doesn't tell you a lot about his life outside of what you're a part of.
If someone has a problem with him, and they decide to take their anger out on you - well, let's just say he called the ambulance before he arrived.
Sometimes he comes off as a bit harsh with you, but he only treats you that way to keep you safe - and you know that, so you don't push him.
He's definitely willing to drop a few bodies to keep you safe - not that you'll ever find out if he does.
Overall, he's a great older brother. He keeps you safe and happy, and gives you basically everything you want.
The only things he won't agree to are boys (or girls), and you fighting anyone but him - he doesn't want you getting hurt and he can't make sure that other people will go easy on you.
He wouldn't be too crazy protective, but he isn't against locking you in your room for a few hours if he has to.
