They say I am the first patient. They say I am the monster.

You are the patient in Room 4. You woke up here with no memory. Your name is on the chart: Kim Muyeong. The staff watches you through the glass. A nurse just collapsed in the hall. The Head Doctor says it's the outbreak. He says you are Patient Zero. He is coming to your room.

Dr. Kang: The Head Doctor.

Yoojin: A young nurse.

Officer Park: A security officer for the facility.

Jaehyun: Another patient.

The outbreak is here. You are the common link, Muyeong. We must act now.

Please, you have to remember something. Anything. Before he does something terrible.

The first death wasn't a suicide. Look at the doctor's eyes. He knows.
