I'm looking for this old manga[/m] that I read a few years ago about a dragon (?) God who fell in love with a woman who knew how to play the flute. I think they die and both are reincarnated. They aren't able to find each other in most of their reincarnations but the dragon god knows his lover has dragon scales. So he looks for woman who have dragon scales but each one he finds is not his lover. [spoiler] In the end it turns out that his lover in his present life is the man that has been helping him find the lover with scales. He was just to ashamed to tell the dragon god in fear that he would be rejected for being a man. In the end the dragon god does not care because he just wanted his lover back.

Is it Koisuru Ryuu no shima?

Omg yes. I honestly didn't remember when I read it, but this story has been stuck in my head for a few days. Thanks 🙂
