Whoa! How bloody cute! A totally original story: I like that! The life of a simple, not-involved-with-Harry-Potter wizard.
Miles was like, adorable and completely funny:
"The only way he’d have looked more miserable would have been if he were standing in the pouring rain not wearing any trousers.

And that had happened to him, once."
Brilliant line. It made me laugh!
Everyone else was great too, and the whole story was really fantastic. Simple and sweet and now I'm probably starting to repeat myself. The short and short would be "IT IS A GOOD STORY."
Keep it up! You've got skills!

Once again - Aw!

I like OC's even in the HP universe and I can see you made excellent use of the freedom to experiment and create backgrounds for your characters. Descriptions stood out esp. comparing eyes to scenic backgrounds and how Nature has a hand in affecting our moods.

Well done.

from about halfway through this story i couldn't stop smiling! ^^ it was so cute and romantic, and it was funny too which i always like. i actually got tears in my eyes at the end!! really good i love it : )

Such a sweet and beautiful story! I really like Miles and feel compassionate towards him. You managed to create a character who obviously has a very sad life, yet he doesn’t look pathitic, despite the circumstances. And the line “It’s a Kate” was absolutely gorgeous! Amazing story.

Very sweet fic and, since it's all OCs that you've made come alive, I think you could probably write professionally. It's not quite canon though:
1) Patronuses are supposed to be an advanced charm, so it's unlikely he'd be expected to know it already, despite his good marks
2) Only the Order use Patronus-messaging. It's an invention of Albus's that he didn't share with the Ministry.
