I think it's very possible.
Think about it.
The movie, Kishimoto said, is about LOVE.
It's obviously not gonna be Naruto and Hinata, and I got a feeling Naruto and Sakura will already be solved in the manga, leaving people to be like "wait.. but the movie?" therefore rushing to go see it... so.... it leaves Hinata falling for this new guy.
And there's tons of other reasons too....
Am I the only one who actually thinks this has a possibility of happening?
