Su Wanqing, the CEO of Anlan Corporation, spends 3.88 million yuan hiring an agency to find a former soldier to pose as her husband so she can deal with pressure from family and friends. However, at a shopping mall, she mistakes Jiang Ye, a retired rescue team captain, for the man she hired. Jiang Ye's codename is Yanlin. Three years ago, he developed post-traumatic stress disorder after saving people from a fire, and he still carries the burden of a strained relationship with his father. After registering their marriage, the two begin living together, and Su Wanqing gradually realizes that Jiang Ye's impressive rescue skills are no act. When a shopping mall collapses and Jiang Ye rushes against the flow to save people, Su Wanqing finally discovers that he was the very man who rescued her from the fire three years ago. The two clear up their misunderstandings and join forces against the antagonist, Chen Xiao, overcoming business conflicts and dangerous crises. Together, they establish an emergency rescue base and embark on a shared future filled with warmth and purpose.
