Song Jae's character embodies a tough, even cruel nature and quite complex, contradictory traits. Playful and arrogant. Does not take what is happening too seriously, often displays a dismissive attitude towards those around him. Likes to cause pain. His actions sometimes border on sadism — he takes pleasure in beating others up, often genuinely depicted smiling gleefully at such moments. Adrenaline junkie. Fighting for him is an end in itself, he enjoys the very process of violence and danger rather than striving for any specific goal like revenge or justice. Despices the weak. He especially hates those who “pretend to be weak” or resort to dirty techniques in a fight. A loner. Despite being a member of a gang, he doesn't trust anyone and prefers to act on his own. It literally “starts” the very process of confrontation, the sense of danger and risk.
