In order to save her seriously ill brother, Su Wan signed a ridiculous contract and became the "contract wife" of Lu Chenyuan, a new technology upstart. He declared coldly: "You are just her shadow, don't expect to get her true heart." She endured the humiliation and acted as a perfect substitute, but in the cold cage day after day, she quietly warmed the ice heart.

What's even more fatal is that she is pregnant with his child! Lu Chenyuan suddenly came to his senses and pursued his wife tyrannically: "Woman, the contract is void, your heart and your child are all decided by me!" And the top-notch AI system he was proud of actually calculated the love he had never said... A bloody storm about substitutes, contracts, and true love swept across!
