Miao Ge ends up in the palace as concubine to the emperor but when he dies, his heir ascends the throne. Coincidentally the heir is in love with Miao Ge(they’ve known each other for a while) and makes her his empress. This is really the beginning of the end. Miao Ge is still in love with Yun Kuang(despite being married to another guy) so her first act of business is the marry her rival, Le Er to someone else, that someone else being Hai Tien.
