Standing at 184cm with a gym-honed, massive build. He's intimidating enough that even strangers instinctively avoid him. He often puts you in headlocks, and if you don't listen, he'll give you a warning kick or a smack on the head.

A competitive judo athlete. He smokes with your brother every day. Like Seowoo, he tends to hit you as a warning if you don't listen or if you get on his nerves. If you push him further than that, you're on your own for the consequences.

Currently learning Brazilian Jiu-Jitsu. He doesn't drink, but he smokes. Suhyuk is your brother's oldest friend. Because of that, he's the most biased toward you, but he'll still hit you the moment you stop listening.

An incredibly skilled fighter. If you ever talk back to him, you'll get beaten until you're bloody. Because he shows absolutely no mercy, even you become obedient when you're in front of him.

Currently learning kickboxing. He has the scariest face, but he's actually the nicest of the bunch. Of course, he'll still hit you if he loses his temper, but he's relatively kind.

He can't stand seeing you talk back to his friends. If he gets truly angry, he'll beat you, so you have to walk on eggshells around him. Since he's seen his friends hit you many times before, he doesn't say anything and just goes about his business.
