Based on this post (not my idea!):

“To Kurt, amortentia would smell like coffee with two sugar and one cream, it would smell like pine trees and the crisp morning air of a winter day, it would smell like cinnamon and winter.

And, no matter how much he wanted to deny it, it would always smell like that stupid raspberry hairgel.”

“To Blaine, it would smell like clean laundry, the warm, dusty scent of a brightly-lit stage, hairspray, piano keys, and mocha.”

We’ll just go ahead and pretend that Gryffindor and Ravenclaw share protions class when they’re tought about amortentia 

I have slightly mixed feelings about how it turned out, but the idea behind it was too sweet to pass up :)
