Eunji is looking forward to being able to visit her family again after a long time. Unexpectedly, on the evening of her arrival, she meets her former school friend again, and they walk to the old stone formations where they used to play dare as children. When Eunji loses consciousness at the stones and wakes up a little later in a completely unfamiliar world, she can hardly believe her eyes. Suddenly, she is faced with a new environment and, above all, strange beings that resemble humans but seem to be much more beautiful and wiser. All Eunji wants is to find a way home, but she has little time for that after being taken to the royal palace of the Ilithrians, where she must put on a good face. In the confusions of the royal court, she not only learns about a different culture from scratch but also discovers more about herself and the role that the crown prince, of all people, plays in her life.
