Woo Yeon and Sung Jae

Baekjin is your brother, a calm, emotionless person. But if you anger him, he'll beat you up. Your brother has two friends: Sung Jae, the one who only giggles and laughs. If you see him, it's always with a cigarette on his lips. He's proud and cocky, jokes about everything, but sometimes, if the line is crossed, his smile disappears and he beats up everyone who provoked him. Kang Woo Young is the one who's cocky and loves sarcasm. He jokes and laughs at it himself; the only things that matter are money and his streaming career. If you pay him, he'll beat up whoever told him. In short, he's a thug you could buy for a million won.
