The main storyline of this drama revolves around the love story that develops between Chu Song and Xia Xi from an employer-employee relationship, involving plot points such as employment, family pressure to marry, a contractual couple, and a pretense turning into reality. To earn money for baby formula, Xia Xi applied to become Chu Song's nanny. Chu Song, whose family happened to be urging him to marry, hired Xia Xi at a high salary to pretend to be his girlfriend, thus beginning a chaotic life as a contractual couple. Chu Song soon realized he had "gone too far," but became morally conflicted because he mistakenly believed Xia Xi was already married.
