Su Qingyuan, the female CEO of the Su family, is pressured to marry. At first glance, she takes a fancy to 22-year-old pure college student Shen Yan and decisively enters a flash marriage. Shen Yan was originally forced into marriage by his grandfather, intending to act ugly and scare away this older sister who is six years his senior, but he is deeply captivated by her Alpha female aura. After marriage, the female CEO dotes on her husband boundlessly, unconditionally protects and backs him up, and lets him play freely; the little doting husband gradually falls and loses his heart from being rebellious and proud, quits drinking and settles down for her, starts a business and makes a counterattack, turning from a playboy young master into a tech new-rich. From a contract marriage to true love, the two go through sweet doting and mutual flirting, running towards each other in both directions, unlocking childhood heart knots, and finally becoming a happy couple.
