The reasons for remarriage can be seen as follows: First, because of children. Two people care about Eiko in different ways, which leads to an irreparable rift between the three people. Qiao Weidong blindly satisfies Eiko, but Song Qian blindly asks Eiko to study. In the end, Eiko suffered from depression. At this moment, the two began to realize their problems. Then I consulted a psychologist, figured out the harm their divorce caused to their children, and began to try to be friends.
Second, there is an emotional foundation between two people. Two people divorced because of Song Qian's strong possessiveness and control, and did not listen to Qiao Weidong's explanation of why he "cheated", which led to the breakdown of the marriage. But in fact, many details can be seen that Qiao Weidong's feelings for Song Qian are still revealed invisibly. For example, he agreed with what Song Qian said; If Song Qian has something to do, he will arrive first, and so on.
In the finale, two people remarried on the day of Eiko's college entrance examination and got a marriage certificate again, encouraging Eiko to do well in the exam. What if there is no emotional foundation? How can two people remarry so quickly? The result is different from before! Therefore, whether it is based on children or feelings, it is most important for two people to cherish the talents in front of them and not wait until they are lost.
