The details of this story just make this post-DH world come alive for me. Snape and Draco running an apothecary, and Harry dropping by regularly but never quite getting up his Gryffindor nerve to ask Severus out. And the curse is so very well thought out, along with the villain of the piece. Grrr.. do not like that person. But mostly it's snarky Snape and Harry pulling things together and turning the curse on its head that make this into such a fun and wonderful story.
