This is fantastic! I love the clumsy, nervous-around-Snape Harry, and the snarky-but-flirty Snape. And the whole bit with the book repeating 'a master and his pet' over and over, and Snape's 'interesting reading material' remark had me howling with laughter and feeling Harry's embarrassment acutely. Simply a lovely fic - which I'm sure I will reread. :D
