Possibility of tomorrow

In a world where everyone believes that dragons don't exist, or if they existed, they are long gone and forgotten, a girl with magic powers meets an otherworldly boy who claims to be a dragon in human skin. Skeptical, the girl doesn't believe him until he begins to tell a tale about the dragons being cursed by a fairy - the same story her grandpa told her so long ago, she almost forgot it. The tale isn't so uncommon, but the original one, the one known by all, says that the king cursed the dragons, not a fairy. So they embark on a mission to break the curse and find out if dragons really do exist.
