I Really Can't Be the Emperor

I am a senior in high school. After the college entrance examination, I couldn't sleep for a while to study the questions, but fell asleep. When I woke up, I was reborn as the emperor of a feudal society in a different world! But I won't be the emperor! Which dynasty is this? Why is this minister smiling so meanly! Why doesn't my queen mother protect me? Why do some people always want to harm me? I'm not crazy, hahahahahahahahaha! Then play music and then dance!
