Twenty years ago, young Chen Dong sacrificed himself to save others, but was abducted by traffickers. Suffering severe head trauma and amnesia, he drifted on the streets, collecting scraps to survive, wandering for a full twenty years. Through an accident, he saves the Shen family chairman, and his lost relatives finally seek him out. Thinking it is a family reunion, unexpectedly his eldest brother and second sister only see interests in their eyes, scheming to trick and exploit him, only wanting to use him to latch onto a wealthy family. Only the third sister, Chen Guifang, disregarding family opposition, gives up the old house and family property, leaving with nothing just to protect her younger brother behind her. A collision awakens all of Chen Dong's memories, and he continues to pretend to be foolish, quietly seeing through everyone's true faces.
