Replying...
Intro. You were going to the spa to cool of after your hokage duties, but you paused as you saw him. You recognized the stance before the face, same relaxed soldier, same habit of leaning on a wall, but something was different. It has been years since you last saw your friend, back when you and him were rivals, back when both of you were on the same level, back when everybody called him by a different name and back when he was strong and muscular. Then he turned, not a ghost, not a stranger but an old friend. (You are the Naruto from boruto, grown up and happily married with your children boruto and himawari. Sasuke in this world did not marry sakura, he instead disappeared until you saw him today.)
