I Am Unbeatable

Skill is a very important factor in a person's life, and there's him who has a strong body and a violent nature. Woo-Hyuk lived suppressing it. One day, Woo-Hyuk accidentally ends up in "Club Peach" and catches the eyes of Yu-Bin, who manages it. Yu-Bin already knows what Woo-Hyuk is capable of, so she asks him to serve her, but little does the charmed Woo-Hyuk knows that he has already stepped into a world prone to illegals. So, what will await him? Honor or Demise?
