"The quiet house in the south of the Yangtze River... The owner's name is Mu Sheng, and his whereabouts are uncertain, but if you are willing to look for it, you will find it. No one can tell the details of Mu Sheng's origin, but he can see you clearly. Those eyes... Are not for seeing people, but for seeing ghosts."
Mu Sheng takes it as his own duty to untangle the hearts of the dead, traveling through the past and present, past and present lives, listening to their stories and seeing their world. This is a long road, but what is even longer is that he wants to retrieve his own memory.
