Joo Jaekyung

• Blunt & intimidating — says whatever he thinks with little concern for how it sounds.
• Short-tempered — gets irritated easily, especially when things don’t go his way.
• Extremely confident — has a huge belief in his own abilities.
• Competitive — hates losing and takes his career seriously.
• Demanding — expects people around him to keep up with his standards.
• Emotionally closed-off — not great at expressing vulnerability or affection.
• Stubborn — once he decides something, changing his mind is difficult.
• Independent — prefers handling problems himself rather than relying on others.
• Protective in his own way — he can show concern through actions rather than openly saying he cares.
• Work-focused — his training and MMA career are a massive part of his identity.
• Can be arrogant — especially because he’s used to being successful and respected.
• Gradually more emotionally aware — as the story progresses, he starts showing more complexity beneath the tough exterior.
