Eyes on the Ceiling

Decorator Chen Mo was working on an old building when he accidentally heard a murder downstairs. To protect himself, he hid in the mezzanine of the ceiling, but became the only witness to the entire murder. The murderer was calm and cruel, leaving no trace, and the residents of the entire building had their curtains drawn, so no one knew about it. Fear made him choose to remain silent, but the murderer had already targeted him, and the criminal police were approaching step by step. A truth hidden above his head is about to drag him into despair.
