Anywho
This is definitely the closest pair to getting canon, the only problem is that where exactly do they progress from here? Who confesses at this point?
Naruto? Well Sakura already knows, Sai basically confessed for him, not to mention Naruto seemed to get his point across when he introduced Sakura as his sort of girlfriend to his dead father
Sakura? Possibly but we need to see her get that "love epiphany" people have been talking about (it would be kind of odd to transition from Sasuke to Naruto off-panel, granted she does have feelings for him but judging from what Yamato and Kishi himself stated she hasn't yet understood them) even then when she finds out she does love him, how exactly will the re-confession go? Will it be like last time only now Naruto somehow believes she's finally over Sasuke?
hence why I said this is sort of in a deadlock, I do think its gonna be canon I just have no idea how Kishi's gonna go about doing it.
