Nan Chu was secretly married to Fu Tingshen for three years, devotedly caring for the family, yet received nothing but coldness. Su Yuning deliberately caused a car crash, and Nan Chu, pregnant with twins, plunged into a river. More than thirty calls for help were all hung up, because at that moment Fu Tingshen was looking after the slightly injured Su Yuning. Having lost her twins, heartbroken, she asked for a divorce. Nan Chu is in fact Aro, a top aerospace research genius. Returning to the research world, she joins CN Technology and exposes Su Yuning's academic fraud with her true abilities. To save her gravely ill father and rescue her imprisoned brother, she once again signs a transactional marriage agreement with Fu Tingshen, playing along in exchange for her family's security and Fu Group shares, completely cutting off her feelings for him.
