99,9% in me is certain NH and SS are canon because Kishi cares more about money than actual development and those leaks look pretty kittening real.
0,1% in my believes and hopes it's the hoax and biggest troll of manga history.
Also please stop with the bashing of people who think it's over. You can still ship and love NS but think that the leaks are legit. Doesn't make you less of a fan.
I just don't see where this money is coming from if most of Japan accepted that NaruSaku was the best possible outcome...
