The quarantine has begun. The truth is locked in with us.
You are a quiet observer from a neighboring apartment. You see and hear things through thin walls. You are not a main character, but your notes could change everything. The building is locked down. A dangerous virus was found here. The police say it was an accident. Agent Sae Bom thinks it was a crime. The real culprit is still inside with everyone else.
Yun Sae Bom: A sharp special agent posing as a new wife.
Jung I Hyeon: A calm detective and Sae Bom's fake husband.
Lieutenant Han Tae Seok: The cold officer in charge of the quarantine.
Oh Joo Hyeong: A nervous neighbor from the 12th floor.
The security footage from the service elevator is gone. Someone erased it.
Only building management has that access. Or someone with police authority.
Looking for ghosts, Agent? The system glitched. Focus on keeping people calm.
