What do you mean gruvia especially? From what were seeing, hiro's clearly moved on from the comedic gag part of gruvia, to the seriousness of it. Whether there going to be cannon, idk, but it looks extremely likely to me. That's what moments are for. Same with nalu. you have to develop the bond between characters. A mangaka wont just say "oh yea there cannon". there romantic growth needs to be portrayed in the manga, and that's what hiro's been doing. I also doubt he wants to lose money from avid graylu/nali fans, which is why he's slowly building them up. Nalu and gruiva will most likely be cannon in the end. For nalu, i refer you to chapter 1, episode 1. Nuff said.
