The Secret Night Tutor

Hong Dan is a court lady with no real experience of her own who is assigned to teach Crown Prince Heon the arts of the night. She knows the theory completely and has practiced none of it, and she has to make sure no one in the palace ever finds out she is still a virgin. The lessons continue under suspicious glances and rumors that spread through the court, and during them Hong Dan and Heon start to notice real feelings forming between them. Crown Princess Seryeong senses the change in the prince and begins pressing Hong Dan, watching her more closely and tightening the situation around her. Seryeong eventually arranges a scheme that forces the truth into the open, and Hong Dan's secret is exposed. She is expelled from the palace afterward.
