Huanbi is nominally Zhen Xuan's daughter, but in fact she is Zhen Xuan's half-sister. Huanbi didn't want to be her sister's maid. She had harmed her sister under the temptation of Hua Fei. When Zhen Xuan knew what Huanbi had done, he not only didn't give up on her, but treated her better than before. Later, because of the elephant incident, Huanbi finally said that he liked King Guo Jun and proposed to the emperor, which fulfilled Huanbi's infatuation.
