Death's Mansion (Zhang Hao x Sung Hanbin)

When 16 students from the elite Zero High Academy are kidnapped and held hostage in an abandoned mansion, their only way out is to solve a series of twisted riddles. But as the puzzles grow darker and alliances fracture, they discover a horrifying truth: one of them is secretly working with the captors.

For Zhang Hao and Hanbin, caught between their budding feelings for each other and the growing body count, survival becomes a battle of trust and betrayal. As fear grips the group and secrets unravel, the mansion's sinister game demands an impossible price-only one of them will walk out alive.

Will love survive in the face of terror? Or will it become the ultimate weakness in a game where the wrong answer means death?
