Aristité was Blessed with a Curse

In the Kingdom of Strandeon, one man from each noble family is required to serve in the Order of the Royal Vine, and Aristité is chosen to fulfill this duty for House Theseus. One day, while the order is carrying out a mission, a witch places a curse on Aristité, saying that he'll lose something important. Everyone in the order thinks that this curse is what transforms Aristité into a woman, but little do they know that Aristité, whose real name is Ariel, was a woman from the start. All the curse did was take away her special medicine that changes her voice. With the help of her friends and cousin, Ariel struggles to protect her secret, but someone in the order seems determined to expose her and land her in trouble...
