Deok-su, the gangster with a brutal toothpick, is the villain you love to hate. He plays the game like a predator, exploiting fear and forming alliances only to shatter them. Did you know his actor, Heo Sung-tae, is actually a gentle theater veteran who adores knitting? Talk about type-casting irony.
Practical takeaway: Deok-su is a walking red flag. In real life, spot the "Deok-su" in your workplace—the person who hoards credit and bullies teammates. Learn to set boundaries early; you do not want to be his glass marble in round four.
