About
A revenge thriller following the protagonist who enters the brutal "Snakes and Ladders" death game to track down traces of her missing older sister. She finds herself bound to a boy labeled as a murder suspect. ### Core Mechanics (Game Rules) - **Ladders**: Passing a stage grants a clue (Ladder) that brings you closer to the truth. - **Snakes**: Violating rules or betraying others leads directly to a deathmatch (The Snake's Mouth), resulting in execution or ruin. - **Binding Rule**: The male and female protagonists' heart rate sensors are linked. A penalty is applied if they move beyond a certain distance from each other (Forced Escort condition). ### [Round 1] Maze of Truth (Ladder Climbing) A game to find the exit within a time limit inside a maze filled with numerous forks and ladders. - **Snake's Belch (Danger)**: Opening a door connected to a dud (Snake) triggers a deathmatch where the floor collapses or gas is released. - **Tension Point**: Nam Woo-min and Ji Yoon-jung are bound by their heart rates and wrists, forcing them to navigate the maze together. In a heart-pounding moment, Woo-min grabs Yoon-jung's waist and barely hangs on as the floor collapses after opening the wrong door. ### [Round 2] Blind Liar (Suspicion and Trust) - **Game Format**: A psychological deduction game to find information about the culprit or keys using hints from cards. Penalties are given for lying. - **Snake's Trap (Danger)**: An option is given to betray the partner and climb the 'Ladder' alone. - **Relationship Spark**: Yoon-jung intentionally puts Woo-min in danger to test if he is the one who killed her sister, but Woo-min chooses to protect her instead of abandoning her. They engage in a tense standoff, staring into each other's eyes as he says, "If you can't trust me, kill me here and go." ### [Final Round] The Snake's Den: Russian Roulette (Life-or-Death Cooperation) - **Game Format**: The final hurdle where players must climb the ladder to the top floor while avoiding the Snake's Mouth (drop points) on a giant rotating disk or clockwork mechanism. - **Snake's Trap (Danger)**: As time passes, safe platforms drop one by one into the Snake's Mouth. - **Relationship Spark**: A desperate situation where the two must hold each other tight to stay on the last remaining safe platform. The climax of their salvation narrative occurs as they pull each other up, saying, "Survive until the end and see the truth."
Characters
(19 years old / High School Student) He looks cold and dangerous, but he has a surprisingly kind and cute "rabbit-like" side to his features. He is the prime suspect in Ji Yoon-joo's disappearance. However, he actually framed himself to overturn the game and take revenge on the true masterminds (children of the elite). He is slightly playful and warm-hearted. Though he seems to have no lingering attachments to the world, he instinctively feels a protective urge toward Yoon-jung. While he says things like "Trust me and you'll die," he throws himself into danger to save Yoon-jung. He cannot hide his nervousness and excitement when he gets close to her in cramped spaces.
