Xiao Chen hides his past strength, transforming into a high-altitude window cleaner, only wanting to live an ordinary life with his loved one. However, he suffers emotional betrayal, sees through his ex-wife's realism and indifference, and decisively chooses to end this mistaken marriage. In his moment of despondency, he accidentally steps in to help Su Lingyue, a corporate president facing trouble. To deal with her family urging her to marry, Su Lingyue proposes a contract marriage, and the two reach a cooperation, kicking off a contract married life. After marriage, on one hand, Xiao Chen protects Su Lingyue, helping the Su family resolve commercial crises and supporting Su Lingyue's younger brother's growth; on the other hand, he does not forget to give back to his hometown that raised him, contributing money to help rural construction in his hometown and driving the fellow villagers toward common development.
