Traversing to another world, Lin En is captured right from the start.
The captor is the antagonist princess from the original work, intending to control him by using him for hypnosis experiments.
In a critical moment, Lin En comes up with a quick-witted plan, feigning the success of the experiment and deceiving her with his acting skills.
But this was only a temporary measure.
Because in the original story, her ending is very tragic, and none of her associates meet good ends.
Hence, Lin En must pretend to be under the hypnosis while secretly being ready to flee at any moment.
But gradually things start to take an unexpected turn.

[I'm happy because people tell the truth when hypnotized.]
[Alone with him, I impulsively kissed him.]
[The feeling was strange and made me lose my composure, fortunately, he won't retain any memory of it after the hypnosis is lifted.]
[So, it's okay to be a bit bolder, right?]
