Since the actual Naruto literature gives us very little insight into this wonderful and complex relationship, here's a post-war, pre-epilogue story of Sasuke and Sakura (compatible with canon. Manga and Novels). It traces the initiation of their relationship, figuring out what they mean to each other, the struggles they go through being apart, their journey together, their wedding, their marriage, and all the sacrifices they make for their village and their nation, but mostly, for each other.
After the 3rd Great Shinobi War was won, the struggle of regaining what has been lost was the next challenge for the Shinobi's of Konohagakure. Sakura's battle in gaining back the bond she had with Sasuke is a challenge she is faced now that the man she love is slowly walking the path of redemption from the darkness he was once plunged into. Will Sakura finally have the romance she had longed for or is she still gonna be a friend for Sasuke?
