I totally get agree with that, but think the thought still works in this fic because its harry thinking it. We all know how Harry is and it makes total sense that he wouldn't be able to see his own faults that might have led to the dislike between Snape and Harry.

Furthermore, I think often its forgotten that Harry disliked Snape right back! He thought he was cruel and greasy and arrogant...

Again, I still think this fic works nicely though. Harry's attracted to Snape because he's seeing aspects of his personality that he kept hidden before, like the genlteness of the kiss!
