How can a divorced, weak woman take revenge on her ex-husband? The emperor knew that she had someone else in his heart, so why did he choose to make her the head of the harem? In order to take revenge, a scheming couple started a scheming contest in the harem: she wanted her ex-husband's family to be destroyed to avenge her son's blood revenge, and he wanted the eldest son who married his ex-girlfriend to be disgraced and never be able to recover. How could such a fake loving couple, who used each other and had their own agendas, really fall into each other's trap?
