The characters and background before the story begins are as follows:
Linchu: A young emperor who was born with a silver spoon in his mouth and grew up in love and sunshine (the previous generations had a strong foundation, and the late emperor's favorite son was not afraid of providing for his willful sons. In a way, it was also considered that the history of the dynasty requires a monarch who is not afraid of trouble).
Lu Mingxuan: He was the top scorer in high school at the age of eighteen. A few years later, he was selected by the late emperor on the recommendation of the former crown prince and tutor, and succeeded him as Linchu's teacher. The late emperor made this choice because he was smart and careful, but at the same time his foundation was not deep and he had not yet been polished to be good at protecting himself. He was sure that he would be loyal and take the blame when necessary. It would not be difficult to get rid of Linchu after he took charge. Lu Mingxuan later gradually figured out the late emperor's intentions, but out of loyalty to the emperor, patriotism, self-sacrifice (and his love for Lin Chu), he was willing to follow the late emperor's arrangement.
Gong has always looked down on Shou, and once the time is right and he has the power, he will abuse Shou. And Shou had long known that such a day would come, and he would surrender with a sense of grievance and hopeless love.
