Minor editing point first: "I swear my part of the guest list is like ten times the length of his, and then again only because we let him have Kakashi-sensei." I am confused by this sentence. Maybe change it to "and that's only because we let him have Kakashi-sensei" or maybe "and it'd be twenty times longer except we let him have Kakashi-sensei"?

Moving on! I really like that their friends are concerned enough about Naruto that they ambush Sasuke and interrogate him about his and Sakura's intentions. I love that Sasuke was making house plans in secret. I adore the war fans, and how pleased Sakura is by their usefulness (and their beauty, sure, okay) and the way they will enable her to be armed during the wedding without mucking up her fancy kimono. I like the way you are working Sai and some bits and pieces of canon in. And I love how underneath his joy for his teammates/lovers, Naruto is still a little worried about the very issue Shikamaru raised, which you can see early on in him not wanting to kiss Sasuke when Sasuke is being cute because of Sakura, and then obviously stated outright at the end; that's a nice echo.
