Behind the Number / FRONTMAN/IN-HO STORY

In a world where desperation often leads to unthinkable choices, Eun-joo awakens in a cold, sterile hall surrounded by strangers. Stripped of her identity and branded only as "315," she is thrust into a series of deadly games where survival demands cunning, courage, and sacrifice.

As the games unfold, Eun-joo forms a fragile alliance with Seong Gi-hun, a man battling his own demons, while catching the attention of the enigmatic and cold Frontman, In-ho. Hidden behind his mask, In-ho orchestrates the chaos with precision, yet Eun-joo's resilience and fire strike a nerve in his hardened facade. Torn between duty and the faint echo of his humanity, In-ho finds himself questioning the very system he enforces.

Amid the blood-soaked trials and betrayals, Eun-joo must confront her own past and the moral cost of her survival. What begins as a fight for her life evolves into a deeper reckoning with the forces controlling the game-and the man behind the mask.

As the threads of fate tighten around Eun-joo, Gi-hun, and In-ho, they must each decide what they are willing to sacrifice-for freedom, for power, or for redemption.
