Pei Jingjun, the "iceberg of power" in the eyes of the outside world who is cold and precise, and who runs a business empire, only has a hidden tenderness towards his wife Su Yining. A marriage with a wealthy family that seemed like a "respectable transaction" was secretly his exclusive favor for treating her as his "only treasure" - washing her hands and making soup, protecting her on snowy nights, and giving him the ultimate preference when no one else was around.
When the new secretary Qiao Shuang, with the ambition of "clinging", tried to intervene with the illusion of "breaking the ice", when external pressure and family grievances came layer upon layer, Pei Jingjun's "absolute desire for private ownership" completely exploded. From guarding her quietly in private to fiercely protecting his wife in public, he used ruthless means to eliminate all interference, just to keep her firmly in his world.
Yi Ning also gradually understood his hidden tenderness from the initial passive acceptance. The two went in both directions in "Storm Front" and finally confirmed that for Pei Jingjun, she was never a "marriage bargaining chip", but an "absolute private property" for which he was willing to subvert the rules and protect his life.
