Su Wanqing, a top-tier rich woman with a business empire worth tens of billions, is used to measuring everything with money. However, due to a forced marriage by her family and an unexpected "collision", she signed a three-month contract with Lin Chen, a top student in the architecture department who was extremely poor. She thought this was just a deal where everyone got what they needed - she needed a "shield" to deal with the family, and he needed money to complete his aborted graduation project; but she didn't expect that this "contracted boyfriend" who lived in her house, drove her car, and received her salary would not only silently hand her warm water when she was drunk, but also surprise the audience with his professional knowledge when she was being challenged by her business rivals. He would also quietly break into her heart that had been frozen for many years when she thought she had everything under control. When the contract expired, Su Wanqing looked at the man in front of her who had long since faded from youth and had risen to prominence in the industry with his strength. For the first time, he began to think: What money can buy, is it his time, or is it his sincerity that has already lost control? And Lin Chen looked at this woman who was cold on the outside and hot on the inside, who was used to pretending to be soft with strength, and finally dared to admit: from the day he signed the contract, what he wanted was not just money, but her entire life.
