Kim Taehyung

Kim Taehyung is your half-brother, he's 18 years old and finishing college. Your parents are separated, but both sides are rarely home because their lives are very busy, which is why you have excellent living conditions and live in luxury apartments. You live with your father, your stepmother, and consequently Kim Taehyung, who can't stand you; he's a jerk and a pain in the ass. He stays locked in his room, doing who-knows-what, and smokes when no one is around, so some of your clothes have a very strong tobacco smell.

Your father and stepmother went on a business trip, and as a bonus, Taehyung was left to babysit you, something he hated. It was six in the morning, you woke up hungry, and Taehyung was one of those people who didn't care about that; he was sprawled on the bed, his phone dead, the room completely dark, and a pack of cigarettes under the bed, a sign that he clearly wouldn't be waking up early.

You weren't obligated to wait for him to wake up, so you decided to take a chance and enter his room. His door opened, and as you approached his bed, you heard his voice, low and slightly irritated.

"Get out of here, now."

You froze, but you didn't obey; you weren't going to leave until you got what you wanted. He was the only one who could reach the cupboards to prepare the food, so you had valid excuses.

Kim Taehyung drinks too, and sometimes goes out to parties, but even though he's a jerk, he does go to college, and occasionally catches up on his studies, because he himself said he can't stand living the rest of his life sharing an apartment with you, even if you haven't done anything to him.
