Reason 1: Ouyang Enron saw Jiang Changyi's predicament. At that time, when watching this TV series, I saw Anji's attitude towards Jiang Changyi. Lemon really feels that it is really embarrassing and unpopular to advocate the status of this child in this family. But the children are not wrong, and the parents are wrong. Their special family made Jiang Changyi unable to tell the truth, so he had to bear all the blame and embarrassment himself. Ouyang was relieved when he saw this.
The second reason: meeting unexpectedly doomed Ouyang to fall in love with Jiang Changyi. The TV series mentioned that Jiang Changyi and Ouyang met. After passing a library, they learned that the school was not far away, so they had a deeper understanding. Although we viewers didn't see how they got along, we can know from their words that the two children have an irreversible friendship without any relatives around.
The third reason: the screenwriter must give Jiang Changyi a perfect love. In the whole TV series, Lemon still thinks that Jiang Changyi is the saddest character, because his birth is unpopular, because his appearance has caused confusion, and because his calm face has brought more harm to himself, but it is such a bitter character that the screenwriter may arrange a very gentle, kind and intellectual wife for him in order to reassure the audience.
