Si Nian, a female college student, woke up and found that she had traveled through time in the 1980s. Not only was she a fake daughter who was kicked out of her home, she also had to marry a divorced old man with two children for the real daughter. Thinking of being a painless mother, Si Nian decisively chose to marry. What she didn't expect was that the old man was not only tall and handsome, but he was also a mobile ATM machine that could explode gold coins at the slightest disagreement. But being oppressed by evil relatives, Si Nian decided to reorganize the family tradition and win over the innocent and rough man.
