In order to repay the huge debt left by her father, Lin Nuannuan was forced to sign a one-year contractual marriage with business tycoon Gu Hanzhou. He thought it was just a cold deal, but he pampered her to no end - making breakfast with his own hands every day, remembering all her preferences, and even clumsily boiling brown sugar water during her menstrual period. Lin Nuannuan gradually became addicted to this tenderness, until late one night, she accidentally heard Gu Hanzhou whispering in the study: "Her taste data... Will take three months." It turns out that all sweetness is a carefully designed taste experiment. And her heart had already fallen in the experiment.
