1. Protagonist: Chen Afu, a modern night market roasted sweet potato stall owner and part-time wedding planner. He fainted because of a competition with the city management on "who is the more nagging". He traveled through time and became the "appointed emperor" of the new emperor of the Yan Dynasty, with the pseudonym "Chen Xuanji". Characteristics: Poor-tongued, good at creating atmosphere, able to graft wedding routines onto government affairs, and carry a homemade "fooling manual" with him.
2. Emperor: Zhao Yan, a 17-year-old young emperor. When he came to the throne, the treasury was empty and the old ministers were dictatorial. He pretended to be majestic on the surface, but in fact he was constantly troubled in his heart. He was so angry by Chen Afu that he wanted to throw the dragon inkstone, but he was always persuaded by his "wrong reasoning".
3. Prince: Zhao Heng, an 8-year-old prince, is naturally timid. He was brought up by Chen Afu to be a "drama artist". He is good at tricking others with his "innocent face" and is the "number one follower" of the emperor's master.
4. Princess: Zhao Yue, 15 years old, is a "rebellious princess" who despises the rigidity of palace rules. She is addicted to what Chen Afu calls "modern entertainment" and takes the initiative to be a "test field for reform."
5. Villain: Taishi Li, a 68-year-old leader of the conservative faction, regards Chen Afu as a "monster in the court". He uses "The Analects of Confucius" to criticize people every day, but he is always choked by Chen Afu's "down-to-earth logic".
6. Core conflict: Chen Afu uses modern methods such as night market marketing, wedding planning, and workplace management to reform the government, battle wits with the conservatives, and help the emperor make money, seize power, and train successors. The whole process is full of chaos but hidden conspiracy.
