Qin Shuyao, the most squeamish and willful little princess in the empire, is nicknamed "The Ceiling of the Essence". An accident bound her to the "Truth or Dare System". From then on, she can get a magical reward for every task she completes - but she must also abide by the contract: if she lies or shrinks, she will be punished by death.
What's even more unlucky is that she bumps into the empire's most confused villain - Regent Xiao Yehan. This villain has a memory comparable to that of a goldfish. Every time he plots to usurp the throne, he forgets his plan. He mixes poison with syrup at every turn, folds kidnapping letters into paper airplanes and throws them out of the window. However, he was so powerful that Qin Shuyao had to sign a "mutual non-reporting contract" with him and was forced to join forces to deal with the situation in the court.
Under the pressure of Truth or Dare, Qin Shuyao used various tricks to complete the task, while watching the confused villain make a series of ridiculous mistakes. However, when the real conspiracy surfaced, she was shocked to realize - maybe this "confused" villain was just pretending to be stupid?
