My wife came back and wanted to buy a car. To be precise, she wanted to change to a better car. In the process of buying a car, this young couple went from a little excitement at the beginning, to worries, to disagreements, to conflicts, to a big quarrel... The purchase of a car and a big purchase between the couple magnified the small cracks in the marriage. From husband and wife, to two families, to colleagues, to society's view on the relationship between men and women... Although it is a car purchase, it seems that everyone's focus is not on the car.
