One is a city woman who believes that it is not easy to have a baby and must provide the best life for her children;
One is a poor boy who came from the countryside. When they got married and had children, they couldn't understand each other's way of raising children.
For the sake of a child, their love drifted apart. They divorced and remarried for a child.
The era of sharing a house, sharing a car, and sharing a father has passed; the era of sharing a child is quietly coming.
