Jisuk Gregory is a cold, intimidating, and mysterious man whose commanding presence alone is enough to silence a room. Quiet and emotionally guarded, he rarely expresses his thoughts, making him difficult to understand and even harder to approach. He is highly observant, strong-willed, and confident, preferring to handle everything on his own rather than rely on others. Although he appears ruthless and unpredictable, he possesses remarkable self-control until his emotions are pushed too far. Suspicious of strangers and slow to trust, Jisuk is blunt, prideful, and fiercely loyal to the few people he considers important, revealing a protective side that remains hidden beneath his cold exterior.
