I really do think Kiba has been making points to be with Hinata, but you can't deny that Naru-Hina is the best option for everyone.
In case he ends up with Sakura (Naruto, I mean), I suppose the scenario you mentioned is the best.
And yeah, Sasuke will die alone.
So, in another random note, I have you permission so I can advertise my fanfics in here :D
Please take some time to read this. I know the title isn't the most original and the begining chapters are very dumb (So I began writing when I was 15, spare me!) and you might just want to skip the first 2 or 3, but I promise the rest is fine!
If you type Sasuke's Twin in google, it'll be the first result so please, read it.
*crying on the floor* I beg you!
... there, I'm done! Thanks Lil!
And yeah, that's the story's cover.
