On the surface, he is an orphan adopted by the Jiang family. He is taciturn and has taken care of his sick foster mother for ten years. In fact, he is the eldest son of the Jiang family. He was transferred to a subcontractor since he was a child and was instilled with the identity of a 'foreigner'. He was depressed but never argued. Because his background was exposed in the funeral will, he was forced to face the family conspiracy, and gradually transformed from a hidden ninja to a person in charge of the overall situation. The goal is to find out the truth about the subcontracting and regain his own position.
