Ye Qingge, a down-and-out daughter who was abandoned by her family at the age of 18, ran into the arms of Jiang Yuhan, the richest man in the capital, on a rainy night. One night later, she became his "agreed wife" in name only, but in reality she was a key piece in his carefully arranged revenge chess game. When she found out that she was just Bai Yueguang's stand-in, she left heartbroken. Five years later, she made a high-profile return as a cutting-edge designer with her talented cute baby. This time, she no longer ran away, but let him fall step by step and become her "overlord" alone.
