Yaoi Manga?

I'm looking for a yaoi manga, but my knowledge of it's plot/characters is kind of vague. I know that it involves a magician/sorcerer (or something like that) as the uke who wants to steal this magic mirror from the seme, who also holds some sort of mythical title (that I unfortunately don't remember). Their ancestors have been fighting over the possession of this mirror for centuries, but the magician no longer has any ancestors and is now the last magician in existence (or something like that). Come to find out, the seme was actually keeping the mirror from the uke not because of this centuries-long battle between their ancestors, but because with the possession of the mirror comes great burden and suffering, which he did not want the magician to go through. Also, I know this is a really random bit of information, but I do remember that at one point the magician brings grapes for the seme (every bit helps, right? lol xD). I hope this is enough, so please help me out if you're able! It would be greatly appreciated :)
