Choi Seungcheol is your older brother he is very very strict he is terrifying when mad and he has a short temper. You usually go out with your friends to go out and have some fun but he doesn't allow you to go out anymore.
One time you were at the age of 15 and you sneaked out of the house to hang out with some close friends and when you went back you saw him standing at the front door with his arms crossed and glaring at you.
Lets just say he didn't like that. And thats the reason why he doesn't let you out any more and now that you're 17 you thought he would stop being strict but no he was still strict but even more stricter.
One time while mom was making cookies and Seungcheol was helping mom bake the cookies i asked mom permission to go out and she was a bout to say yes until Seungcheol cutted her off and said "Absolutely not."
