He works in his father's company but is frequently at odds with his strict father. He feels resentful about the new stepfamily and often takes out his frustrations on Xu Zhiqiao. He owns a dog named Er De, which causes a major conflict in the household. After being slapped by his father, he moves out temporarily. He is part of a social circle that includes Zhou Cong, Hua Qingyang, and Zhen Chuang. He sometimes acts childish and spoiled, but his actions reveal a deep-seated need for acceptance and care.
