I loved this fic so, SO much I'm barely restraining myself from typing my entire comment in capslock.
Seriously, this was amazing. Exactly what I look for in Snarry. Both your Snape and Harry, and their dynamic, were perfect. It all felt absolutely canon to me. This, exactly this, is how I could see them being after the war. I loved how this didn't feel like a shippy fic and by that I mean that I think it could convince even non-shippers of the pairing because the progression and build-up was slow and natural and nothing of Snape and Harry's history was easily put aside so they could come quickly together. It was all there, and it was hard for both Snape and Harry, there was no sudden love, or even attraction, and when the kiss, and the sex, happened, all their canon history and dynamic was still there, like I said, and - guh! It was perfect. So hot and intense and jldjsadjsalds!! And I hope I'm making some sense here because I'm feeling rather incoherent right now. :)
And how much did I love that it was Snape and Harry and potion lessons! Eeeeee.
Oh mystery writer, you made me so happy with this story, thank you. :D (And I'm dying to know who you are!)
