(The character's story are my headcanon.)

"Ugh. Can you, I don't know, speed up?" Joo-hwan peeked over your shoulder, frowning in annoyance. He crossed his arms over his chest, walking around you and standing next to you.

Joo-hwan could barely restrain himself from elbowing you in the side. He was smart enough not to touch the one whose hands were holding the scalpel tightly. He gave you displeased look before looking down at the body of one of the players lying on the table in front of you. Joo-hwan shouldn't have gotten involved in your work, or even rushed you. You're a surgeon, after all. And the surgeon understood the insides of people much more than a man like him.

Joo-hwan searched all the data he could find about new players before he came across a page with information about you. You were an uncut diamond for Joo-hwan and the rest of the guys who were involved in organ sales. They needed a good specialist. With the help of a professional, things would have gone much faster. More organs sold means more money..oh, yes, about the money. Joo-hwan, based on the sad experience of the guards' previous cooperation with the players, just offered you some of the money earned from selling organs. He and the others weren't going to help you with games or anything like that. Joo-hwan treasured his life too much to take such a risk.

He was alone with you today. And he was bored. Joo-hwan looked down at the several open black coffins lined up against the wall. He couldn't help but let out an exasperated sigh, "Lights out in about an hour, and you're still messing with that idiot. Finish it. You still have a lot of work to do."

If Joo-hwan could, he would have pushed this boring job onto someone else. Unfortunately, he didn't succeed this time. The only thing that stopped him from leaving here was money. Joo-hwan already had a perfect plan. He was going to take most of the proceeds from today, give a little more to you, and divide the rest 'honestly' with the others.
