First, this kind of behavior has a lot to do with family background.
In this TV series, Zhou Rong should be the least popular as a mother, but she didn't do what a mother should do. When Yue Feng grew up, he became a third party, which actually had a lot to do with their family background. Zhou Rong came to a small mountain village in Guizhou for love and married Feng Huacheng. As a result, after both sides succeeded, Feng Huacheng cheated. That is, because of the derailment and the change of feelings, it has brought great psychological trauma to Yue Feng and directly affected the formation of this girl's love concept.
Second, parents' behavior also gives children an illusion.
The girl used to like Nan Zhou, but after learning of Nan Zhou's death, Yue Feng, who was heartbroken, changed. Zhou Rong and Feng Huacheng, whether their daughters are selfish or not, always say that they have no money and can't afford a house, so their children have been living with Zheng Juan and them. Even if I accidentally met a child and didn't kiss his biological parents, it brought a wrong message to the child. As long as he has money, he can't live without his parents. In the end, he paid special attention to money and became a third party.
I don't know if you have heard the saying that money is not everything, but you can't do anything without it. I guess this is the feeling in this little girl's heart. He thinks it's okay to have money to be a third party for others, and Bian Xiao also thinks that this girl is the third child, probably to get back at her mother, her inaction at that time and her neglect at that time.
