How A Psycho Does XX

Yu Seong-U is a dedicated and highly dependable prison guard, known for his strong sense of duty and unwavering conscientiousness. He takes pride in maintaining order within the facility, carrying out his responsibilities with a quiet professionalism that earns him respect among both colleagues and inmates. For Yu Seong-U, the prison is simply his workplace—a place where he serves his role diligently day after day, unaware that his routine life is about to be profoundly disrupted. Everything changes when a new inmate named Baek U-Hyeon arrives at the facility. Far from an ordinary prisoner, Baek U-Hyeon is a calculating criminal who has spent the last eight years meticulously orchestrating a plan with one singular goal: getting close to Yu Seong-U. His incarceration is not a setback but rather the final, deliberate step in a long-conceived scheme. As Baek U-Hyeon settles into the prison environment, the carefully constructed boundaries between guard and inmate begin to blur. What unfolds behind the prison walls is a tense psychological narrative, as Yu Seong-U finds himself drawn into an unsettling dynamic with a man whose obsession has been years in the making.
