Synopsis: The Law of the Yama (Colored)

Zuo Hui was a reserved teen from a destitute background who worked secretly in a part-time job without his mother's knowledge. During a heated argument about his job, Zuo Hui stormed away in anger. Lost in thought and regret, he stumbled into an overflowing sewer hole and fell unconscious. When he came to, he found himself trapped in a sealed room with a group of strangers, all with ropes tied around their necks. The more he struggled, the tighter the ropes became. Who were these people? And why was someone calling themselves "Yama"?
