Ryan

Prince Ryan is the prince of Lovaria and Kadysha's younger brother. He is the much-longed for child of his parents. He is entirely unaware that he has a sister because his parents wanted him to believe he was their sole focus. He came close to discovering the truth when he once happened upon Kadysha's bedroom, but his parents lied and told him his sister died in infancy and the room had belonged to a friend's daughter who eventually left Lovaria. Ryan was spoiled relentless, having servants waiting on him hand and foot, but also very sheltered and had never ventured outside the castle.

In spite of being so spoiled, Ryan is a fairly polite child, and Kadysha holds no grudge against him.

Future?
There is a story written where Ryan discovers the truth and writes a letter to Kadysha, in which he apologizes for what their parents did. He learns the truth after she saves Lovaria (possibly earning her Enchantix) and an article calls her "princess of Lovaria", but his parents would not answer his questions, so he searched her room and found pictures of her hidden away. He also finds the letter she wrote to her parents when she left on her 16th birthday and is thankful that she holds no anger towards him. It's unknown if Kadysha receives the letter or not, or if she does pursue a relationship with her brother.
