To protect her brother, Hari enters the royal palace disguised as a eunuch. Despite her worries, life as a male court attendant turns out to be surprisingly peaceful.

At least, until she is suddenly assigned to serve Prince Sohyeon, Lee Ryeong, known for his striking beauty and well known attraction to men, in his private chambers.

“From now on, you will attend to the prince at night.”

That very evening, Hari is ordered to help arouse the prince, a task she has no way of fulfilling. Her panic spirals, and in the chaos, her greatest fear comes true, her true identity as a woman is exposed.

“You, you are a girl.”

Now discovered in the most dangerous place possible, Hari must find a way to survive the palace, its secrets, and the gaze of the prince who holds her life in his hands.
