Synopsis: Lady Crystal Is a Man

Crystal Rotary, the youngest daughter of the Rotary family, rarely leaves the confines of her own separate building due to her frail and weak body. What no one knows is that Crystal is actually a man. In a family where only women are allowed to live, Crystal's goal is to flee the Rotary family and live a normal life. However, in order to survive, Crystal must disguise himself as a daughter and live like a dead person. When he attempts to leave, he is confronted with a marriage proposal. Desperate to escape, Crystal sends a proposal to Duke Pentrin, who is politically opposed to the Rotary family. To Crystal's surprise, Duke Pentrin accepts, leading Crystal to flee to his castle. There, he meets Illyan Pentrin, a cold and cruel man who they wed. But on their wedding night, Crystal is shocked to learn that they will not consummate the marriage due to Illyan's impotence.
