The Hand That Pushed Back

At the Danha Vocational Rehabilitation Center's occupational therapy wing, safety manager Choi Su-kyung was found dead beneath a hydraulic lift platform on the sheltered workshop line—a protected work area designed for people with disabilities. That day she'd been assigned to the line as a substitute, inspecting hazard zone markings, and the line had been running normally right up until the accident. The descent lever was jammed all the way down and locked in place. Interrogate the five people entangled in this death and determine whose hand pushed that lever and held it there.

Compartment

Nam Si-yeol, an outsourced fire-safety inspector, was found dead in the morning inside the heat-acclimatization training room of the Danha Fire Department Psychological Recovery Center's training wing. The fire door was locked from the outside, the heat-source control was fixed in maintenance mode, and the cause of death was severe heatstroke from prolonged high-temperature exposure lasting over two hours. Interrogate the five people connected to this center that night and determine whose hand brought this death.

Sealed Night

At the Danha Crime Victim Recovery Support Center's temporary shelter wing, new night counselor Lee Arin was found dead in the morning. It was her first overnight shift, and while she slept in the first-floor duty room-cum-protection room, carbon monoxide filled the space. The water heater operated normally, but every air intake in the building had been sealed during the night. Interrogate the five people surrounding this death and determine whose hands sealed the building.

What Was Washed Away

Late summer evening after the rainy season ended, humidity still clinging to the air. The Danha Chemical Incident Recovery Support Center was running its usual evening programs. In the annex washroom of the program building, Park Ha-min (31), a new contract worker assigned to routine disinfection, was found collapsed inside a sealed booth. He died of acute respiratory failure caused by inhaling high-concentration chlorine vapor—chemical pulmonary edema that drowned his lungs from the inside. Entering the booth to wash himself appeared nowhere in his work orders, and the wash line feeding the booth had been opened without passing through the dilution stage. That evening, five people were entangled with this death. Interrogate them and find the hand that sent him into that booth.

Wakeful Hands

Lee Yeon-ho, an external contract auditor responsible for verifying regulatory compliance at the Danha Regional Trauma Recovery Support Unit, was found dead late one rainy summer night in the third-floor lounge of the headquarters building. The cause of death was anaphylactic shock—a systemic allergic reaction that caused airway swelling and circulatory collapse. The door was locked and no emergency call was ever placed. He had scrutinized four contracted sites, earning enmity everywhere, yet his findings were always correct. Interrogate the five people who remained in the building that night and determine who led him to his death.
