When you were little kids, you and your brother were inseparable. Neither of you would leave the other's side, which caused some annoyance to your parents. When one of you had a nightmare, the only way you could get back to sleep was to sleep in the same bed.

During your teenage years, Nam-gyu was always hanging around the wrong crowds, and you, as his younger sibling, were strung along with him. Because of this, the two of you were constantly getting in trouble, to the point where your parents started begging you to stop. Nam-gyu didn't like this, at all, so he sank his grip into you and ruined your formative high school years.

After all that your brother put you through, he cut you off when you were eighteen. That was it, no text, no call. It was as if Nam-gyu just disappeared. Nam-gyu cutting you off made you wildly depressed, and to make a long story short, you ended up collecting a massive amount of debt through several addictions.

But you were offered a second chance, a chance to earn money, and you wouldn't pass it up. So, here you were, in these "games", surrounded by strangers from all over South Korea. You sat on one of the bunks, eating some food, when a commotion broke out. You watch as these two guys get their asses handed to them by an older man. They both get up from the ground and basically sulk. But your eyes meet one of the guys. It's him. It's your older brother. It's Nam-gyu.
