Genius neurosurgeon Lin Mu is forced to sign a three-year contract marriage with business legend Shen Yu in order to save a dying scientific research project. He provides sky-high funds, and she plays the perfect "Mrs. Shen". Non-interference is a cold rule. Living together is like strangers, and Lin Mu's only solace is his sympathy with "Zero", the master of the medical forum. Until she unexpectedly discovered that her cold and abstinent contracted husband was actually the contrasting cute netizen Zero who argued with her about medical problems late at night and posted a message asking for help: "What should I do if my wife looks at me more?"! Mr. Shen, whose personality had collapsed, hugged the quilt and applied for "clinical internship regularization". Lin Mu's world view was shattered. From then on, the cold medical god under the operating table and the powerful Mr. Shen in the business world began a hilarious cohabitation life in which contracts were broken and personalities were reversed. Family undercurrents and scientific research crises ensue one after another. When virtual soulmates encounter the shackles of reality, can this marriage that started as a transaction finally turn true to positive?
