College student Si Nian wakes up one day to discover that she has traveled back to the 1980s. Not only is she a fake heiress who has been kicked out of her family home, but she is also expected to marry a divorced older man with two children in place of the real heiress. Thinking that becoming a mother without the pain of childbirth sounds like a great deal, Si Nian decisively agrees to the marriage. What she never expected is that this older man is not only tall and handsome but also a walking ATM who showers her with money at the slightest disagreement. However, faced with oppression from her wicked relatives, Si Nian decides to set the family straight and win the heart of an innocent, rugged man.
