A portrayal of how Sasuke copes with his trauma and sins from the past. In another lifetime, he finds he could have been a great jutsu teacher. Time travel Canon divergent fic, starts with angst, but morphs into adventure. Major Team 7 friendship buldings, highly Sasuke-centric, maybe eventual Sasusaku. Post-war, repentant Sasuke! Genjutsu Sakura! Strong Team 7!
