Xiao Xiaoxiao, an ordinary accountant, hopes to get rid of the troubles caused by his original family. He reaches a prenuptial agreement with Song Yelin, an entrepreneur who is not good at expressing emotions, and starts a contract marriage. As they spend time together day and night, the two warm to each other and gradually develop feelings for each other. Faced with her father's unreasonable demands, Xiao Xiaoxiao responded bravely with the support of Song Yelin. Song Yelin's old acquaintance Qu Qing returned to China and joined forces with competitors to create a crisis. Xiao Xiaoxiao lost her cowardice and joined hands with Song Yelin to unite business partners to resolve the crisis legally. After two-way healing, the two confirmed their sincerity. Xiao Xiaoxiao became pregnant successfully, canceled the agreement and held a Chinese-style wedding, realized self-growth, and embraced a stable and happy new life.
