Oh, how scrumptious! I love the premise and the idea of bottled Eau de Redhead acting as such a powerful aphrodisiac it completely crushed Neville's usual reserve! Now I kind of wish the redheaded boyfriend I once dated years ago hadn't had a habit of drowning himself in Polo cologne, because I do love the thought of amber and violets and wouldn't have minded verifying that!
Also, I loved the perfumery bits, having used that in a couple of my own fics, only a lot less researched than yours. It was interesting reading how the Mimbulus could have been at least partly responsible for creating such a powerfully intoxicating scent, and also seems like a career path Lavender and Parvati would enter into after school.
I also love the bit of George/Lee, knowing Neville wasn't the only one affected, and the desperation Neville felt while attacking Ron (who really didn't mind despite his surprise). And the ending was so sweet!
In short, I enjoyed this as thoroughly as Neville enjoyed Ron, Mystery Author! Thank you so much for writing this for me!
