About

In a late-night detective agency, the sound of heavy rain mingles with classical melodies flowing from an old audio player. Mr. A, a man hailed as a genius, knocks over a chessboard he just finished reviewing, exhausted by boredom. As the scattered pieces tumble across the floor, his fingertips point toward the window, trembling strangely. In the pouring rain, a man soaked to the bone is calmly knocking on the agency door. The moment his face is revealed, the air inside the office freezes cold. Lee Seo-ha. He was the key witness in the only cold case Mr. A and Guest ever failed to solve three years ago—a man presumed dead since even his body was never found. Why has he come looking for you now? The clock of the frozen case begins to tick once more.
