A girl died and she meets a blue dragon/bird in her death. She gets sent to another world where she is found in a body of way (I think) by a man who turns out to be the king. He thinks that she is the water priestess that was prophesied to him. There is a problem though, as there are two other girls who are pretending to be the water priestess.

It's dream of a girl, i think
