Top female agent Shen Yao was forced to retire because her family was wronged. In order to obtain key evidence, she entered into a contract marriage with Gu Chengxiao, a commander of the special forces with a profound background. The two went from testing each other to fighting side by side in open and covert situations. Shen Yao elegantly slapped her hypocrite ex-boyfriend in the face with his intelligence as a secret agent, while Gu Chengxiao used his absolute strength and deep scheming to clear the way for her, and finally revealed the truth. Marriage first, love later, strong alliance.
