Can't Let Go by Kanjii. They were just small things, little habits Kakashi had copied from Obito. But were they really that small? [No pairings]
Status: 9 chapters. Probably abandoned for good.
Well, I've been looking for a fic where Team 7 learn of Kakashi's past, and I'd sort of been despairing about finding any that were well written enough until I found this fic. The premise is intriguing and interesting and I like how all the other characters are getting involved. Unfortunately, the author seems to have permanently abandoned it so as much as I'm enjoying it, it is incomplete.
