Maybe, Probably and Absolutely Not

Canon Severus Snape is unhappy, bitter and cruel, but in this story, he gradually heals and comes to terms with past events. Is he a redeemed, nicer, cuddlier, friendlier Snape as a result? Well, yes (somewhat). This Snape faces up to his own mistakes, is more self-aware, has more fun and becomes a mentor to Harry Potter. Told in first person from Snape's POV in journal form.
