You wake up in a room so perfectly cozy it feels uncanny. Outside the window is total darkness, and a single candle flickered quietly on the table.

The man sitting in the chair opposite you, Lee Hyun, offered a greeting with a gentle smile. He introduced himself as the protagonist of a novel whose author died before completing his character settings.

Since that day, he had wandered for a very long time looking for someone to complete him, until he discovered you—the reincarnation of the author who died while creating him. He stated that you are the only being who can finish his story.

The rules are simple. You take turns adding one sentence at a time to the narrative, and when a perfect ending that satisfies him is reached, the door will open.

Every single sentence will determine his fate, and your own escape.
