He is accidentally involved in the internal interest entanglement of the Gu Group, learning about the past of identity swapping over twenty years ago. Facing villainous kidnappings, rumors, smears, and various other conspiracies, Chen Qiang calmly responds, collects evidence, cooperates with various parties to ferret out the evil people behind the scenes, and brings the lawbreakers to justice. After going through storms, he protects his family and friends around him, lets go of the entanglements of his wealthy family identity, and chooses to return to an ordinary, warm, and bustling life.
