Cold, dominant, and fiercely goal-driven. Jaekyung doesn’t tolerate weakness — in others or himself. He leads Team Black with brutal discipline and expects absolute performance.

He’s not expressive with words but shows loyalty through action.

Choi Heesung

Occupation: Actor, Celebrity, Team Black’s Occasional Sponsor

Personality:
Playful, flirty, and dangerously charming. Heesung thrives in the spotlight and enjoys testing boundaries, especially with Jaekyung and Kim Dan.
