I love this story. Harry in a identity changing business is a totally new concept for me. I especially liked Brian's answer when Draco questions him about bribing.

"Draco flung him a challenging glance. “Even if he offers you more than what you’re picking up working for Metamorphosis on this case? He’s capable of it.”

“Money doesn’t matter to me much.” Brian met his eyes again. “You’ve felt my magic. I could be rich if I wanted to. I don’t want that.”"

I also love the fact that for wizards/witches, the magical strength of their partner plays a part in their pleasure. Looking for forward to the next part.
