There is one fundamental life rule for sane people: DO NOT, UNDER ANY CIRCUMSTANCES, MAKE DEALS WITH THE DEVIL. And what did I do? Make a deal with Regulus, of course. Now all I have to do is pretend to be the perfect, respectable pureblood girlfriend of Regulus Black, and he, in turn, will make my crush jealous enough to finally make a move. Hopefully. Win-win situation... right?
