Hmm, no, I don't think it's creepy/stalker-y. I think it started out as Severus trying to keep a promise and turned into something more completely on accident. Of course, now we can hope that Harry learns to care for him as well, hmm? *grin*
I really liked this. I especially like the fact that Severus was responsible for growing Harry's hair back- that's a really good detail to put in there, and adds realism to the story as well as characterizing Severus very well- that he couldn't let Harry suffer through that. I really liked this- excellent job. Thanks so much for posting this. *hugs*
