Blood does matter

This is my first ever fic. A spin on two classic storylines - PurebloodHermione&Dramione. EWE, but for the most part canon compliant. This will be a multichapter fic with several different minor plotlines added to the main two. Mostly funny fluff, some wizarding science&minor drama for plot. HG/DM(slow burn) HP/LL(and many other pairings) M, cuz better safe. Please review!
