In order to preserve the family business, Zhong Mingzhu, the eldest daughter of the Zhong family in northern Beijing, entered into a business marriage with Meng Jinbai. The two originally thought it was just an exchange of interests, but they gradually became attracted to each other as they joined forces to break the situation again and again. Meng Jinbai looks cold on the surface, but in fact he protects her silently, using actions to break Zhong Mingzhu's psychological defense. Zhong Mingzhu takes off her guard in the game and discovers that her most tacit ally is actually her closest lover. When family property disputes and emotional undercurrents ensue, they grow from an alliance fighting side by side to each other's strongest reliance.
