But his wife, Wei Qinghe, unexpectedly hears his inner thoughts, and eventually the entire Wei family gains the ability to hear his mental commentary. Their initial disdain and suspicion gradually turn into the realization that this seemingly worthless son-in-law is far more extraordinary than he appears.
