In order to save the family from crisis, the independent and intelligent designer Su Wan was forced to sign a contract marriage with the powerful business emperor Lu Beichen. She thought it was just a cold deal, but she didn't know that she was Bai Yueguang, who he had been secretly in love with for ten years. Under Lu Beichen's extreme pampering of "careful at every step and attentive to everything", Su Wan gradually melted into the gentle web he weaved. When the contract expired, past conspiracies and misunderstandings also surfaced. They finally confirmed each other's feelings in a frank manner, turning the contract into a lifelong commitment.
