Very cute!!! :-) I like it!
AAAWWWWW!!!!! That was so beautiful!! I love your take on Remus' personality! There is really very little anyone really knows about what he was like in his school days and Lily is just as hard to create a personality for just based on what we know from the books but that was amazing! Keep writing!
This was a sweet story that has an almost wistful tone. I'm a girl in love, not a boy in love, but I assume that some of the emotions are similar - the intoxication and the lingering thoughts that seem to overwhelm everything. I thought Remus in love was written wonderfully - he viewed himself fearful of rejection, thoughts were all consuming, he lashed out at his friends, etc.
I was first struck by the fact that fourth years don't usually have access to the Prefect's bathroom, but I didn't let the detail bother me.
Remus seems to be a secretive, selfless person, and this portrayed him no differently, hiding his feelings for someone he cares about to not hurt his friends and for his fear of rejection.
Even as a young man, I'm not sure Remus would have such depressing, resent thoughts about himself. While he always seemed to accept the realities of his situation - the reading of the werewolf registration and arguing with his friends about it is a great example of this - it seemed rather out of character for him to think about himself as a "filthy half-breed." I understand why you emphasized some of his thinking - it made the ending tie out beautifully - but I thought this line in particularly was a bit too much.
Overall, it was a lovely read.
