Luo Qianyu, a genius and sick CEO, was told by doctors that he would not live to be thirty. In order to deter the eager family and business enemies, and for the unfinished business ambition in his heart, he urgently needs a "marriage" as a talisman and smoke bomb. He chose Shen Wanxing, a cold and charming forensic doctor who returned to China for revenge and had a secret. She had what he needed, and he provided her with a stage and shelter for revenge. With a contract, each takes what they need and join forces. However, when he dreamed back at midnight, she always stayed by his side when he was ill and calmly administered acupuncture; when he discovered that her "enemy" was actually intertwined with the secret past of his family... This flash marriage, which began with mutual use, gradually got out of control amid conspiracy, temptation, and life-and-death crises. When the strongest spear (ambition) meets the deepest secret (sadism), and when the weakest body holds the strongest will, can they fight their way out of the thorny business wars and unsolved cases and find the truth and... Sincerity?
