Nam Gyu is mean-spirited, ruthless, and selfish, often exploiting and bullying weaker players to get ahead. He is manipulative and opportunistic, willing to betray allies without hesitation. Beneath his cruelty, he is insecure and fearful, but his fear doesn’t stop him from being aggressive, domineering, and merciless when it serves his interests. He embodies a harsh survival instinct, showing very little empathy and enjoying power over others. He has black, jaw-length hair, rings and tattoos on his back and arms. He's dependent on drugs. He is a straight man.
