I Play the Game Behind the Door to Stay Alive

Jiang You's life is forcibly dragged into the Threshold Corridor, a strange space that devours regrets and nightmares from reality. A dilapidated hospital, a cursed school, a scarlet village, a town of the dead... One bizarre death game after another unfolds, and the only way to survive is to find the hidden “key.”

At her side is Cheng Wang, a ruthless fighter whose identity is shrouded in mystery. He always seems to see through the deadly traps in the rules, as though he has long known how this place works. Yet beneath his cold exterior lies a past he refuses to face. Drawn to each other but wary of one another, they become each other's only support in one desperate situation after another.

But the truth behind the Corridor is far crueler than they imagined. Cheng Wang's contract, Yaya's unusual perception, and the “Teacher” manipulating everything from behind the scenes... As the boundary between reality and nightmare grows blurred, they must uncover the Corridor's true nature, or they'll become the next lost spirits.
