It is said that there was a pair of loving lovers in ancient times. One of them passed away due to an accident, and the surviving one also died of illness due to longing. God couldn't bear to let them part ways, so they were reincarnated as a pair of twins. It is obviously a good meaning for dragon and phoenix to bring good luck, but there is another saying among the people - after the twins of dragon and phoenix are born, one of the sons will not survive. The Bai family was a famous family in the dynasty. The current patriarch was not only young and promising, but also a good man who loved his wife and was praised by the emperor. The couple was very loving and had an heir a year after their marriage. Patriarch Bai, who thought that giving birth to twins was a good sign, discovered something unusual at a certain moment. His son and daughter seemed unable to live together. When two children met, something was bound to happen to one of them. In order to protect the children, he was forced to separate the two children. The daughter stayed with him, while the son was sent to his younger brother. In this way, the two children lived peacefully until they were nineteen years old. But what he didn't expect was that the bond between twins made them recognize each other again in a strange way.
