Marvelous story! I really enjoyed the slow build-up of Harry's guilt. He started out believing that he could handle the bond, and was really hit hard at the beginning of the Courtship when he realized how submissive Snape was, and how much he liked it.
The ears were just too, too hot!
The angst, sex, tension, and denouement were masterfully maintained. I particularly liked the gentle ambiguity of the ending--that Harry got the snarky Severus that he wanted, but he also got a Severus that didn't belittle and demean his former student, AND he also got someone that he was searching for all his life--someone who would love and cherish and put Harry first. It makes you wonder if it was fate, chance, or the bond reading Harry's desires that created the Severus that we saw at the end...
