Your Majesty's Pet

The violent and perverted emperor and the stubborn and cold minister! The beginning is very sad, but the end is very sweet!

Three years ago, a palace coup occurred, and Du Yuzhang abandoned his family just to save the life of his beloved. Unexpectedly, his beloved ascended the throne and no longer had any pity for him. From then on, during the day, he was the left prime minister Du Da who was powerful and above everyone else; at night, he became the plaything of Du Yuzhang, who was tossed around in the palace and under one person.
