To secure her younger brother Jiang Ruoheng's position as heir, Jiang Ruolan set everything aside and entered into a marriage alliance with Yan Chu, the powerful head of the Yan family. She thought it would be nothing more than a mutually beneficial arrangement, never expecting that the man rumored to be cold, aloof, and unfeeling would stand up for her when her family made things difficult, or offer her warmth when she was exhausted.
Within the Jiang family, Jiang Chengyu's relentless pressure, Jiang Jingyao's open and hidden attacks, and Jiang Shuyun's concealed schemes kept her constantly on her toes. By Yan Chu's side, his quiet protection and Fu Shixun's well-intentioned advice warmed her heart. From their initial icy politeness to the tentative push and pull that followed, Jiang Ruolan gradually fell for Yan Chu's tenderness, while he had long since fallen sincerely for this resilient, intelligent woman. Once love pierced the façade of their marriage alliance, could they hold on to each other amid the fog of family rivalries and turn this transaction into a lifelong promise?
