The heroine, as a "waste" young lady who was abandoned by her family, was forced to enter into a business marriage with the rumored ruthless CEO of a top wealthy family, Shen Sihan. She originally thought that this would be a formal marriage that would be respectful and even full of cold violence, and she was going to play the role of "the wife of the pseudonym CEO" according to the script, but unexpectedly discovered that the overlord was a completely different species before and after marriage. In front of others, he is a decisive and unkind business king; in private, he is a love-minded husband who strictly follows the handwritten "Guide to Beloved Wife". He even hides in the study and sends frantic messages to the love counselor because of the heroine's occasional smile. This marriage-first-love-after-marriage relationship of "one wants to have a heart but not a heart, and the other just wants to follow the script" started with the pull of two-way misunderstandings. When the heroine gradually fell into decline, the "mission" that the boss was forced to complete due to family trials revealed the cruel truth.
