The (real) saint found out her handsome friend, Alex, was the prince of the neighboring kingdom after she was exiled. He asks her to come with him and save his people. Of course she'll come!

Tiara, who has special power to heal people, had been working in the Imperial Court of Lerys since she was just a girl.
As a "Saint," she healed wounded or sick people every day until she was exhausted.
However, one day she was accused of pretending to be a saint--the second princess, Isabelle, who hated her, wanted to show how powerful she is.
Tiara thought for a moment...she was never happy here. It would be better to be kicked out of here and live a life of her own!
While she was trying to find a book to read before leaving, she met Alex. When he heard what happened, Alex suddenly said "Why don't you come to Ekwald, my land?"
Tiara never knew that he was the prince and the strongest dragon knight of Ekwald! Tiara's journey begins.
