In order to repay family debts, Su Qingyuan signed a three-year contract marriage with Lu Shiyan, the rumored autistic heir to the Lu Group. She is cold and independent, and regards marriage as a transaction. However, when they live under the same roof, she discovers that the autistic CEO is just not good at expressing himself, and will even silently take care of the details of her life for her. Faced with the outside world's doubts about Lu Shiyan and the family's difficulties, Su Qingyuan responded with a cold attitude and supported him. When the contract was about to expire, she thought she could escape unscathed, but found that her heart had already fallen. Lu Shiyan also gradually opened up his heart in her company, telling him in his own way: The contract is fake, but my love for you is real.
