So. Much. Love. This piece is great in so many ways that I hardly know where to begin!
The drawings are perfect, the story's a winner, and the humor's great, with too many funny lines to quote. What I like best, however, is the fact that the entire story exemplifies the comfortable, affectionate romance of real love and everyday life. To me, this is far more romantic than a shower of rose petals and grand gestures.
I'm also boggling at the amount of wonderful little details you've included: Eileen's portrait, Harry's heart boxers, Snape's french press and early morning stubble...and OMG, reading glasses!Snape! I love a Snape with glasses.
So, anyway, I really liked it, just in case you couldn't tell. ;-)
