Moreover, the relationship between the two of them is gradually getting a little wrong, but what should they do with their relationship in such an era? Facing all kinds of pressure, Shen Yi couldn't accept it at all. People can't accept this kind of feeling in the 21st century, let alone in the backward 1980s!
