So, a few months ago I wrote my first and only Severus/Lilly one-shot. It's close to my heart, as is the pair it's written about, and I'll post it here for the enjoyment of others. It's on Ff.net and I've provided the link below. Do enjoy, and stop by to leave a review if you feel so inclined.
(sigh) I do love them as a pair. I so wish that they could have lasted. In a parallel universe, perhaps they could.
