Let’s say hypothetically they really did date each other (not saying they should), would anyone really object to that? Seems like this is one of the most supported male female pairings in the vtuber world so idk.
There would be a minority opposing it for sure. Also from what I've seen in translated clips, I think Hinano's contract doesn't let her disclose publicly if she is dating or not (I could be wrong). There is also the charm of two tsundere's never admitting to dating/liking each other romantically too (Like Love is War, but not exactly, but also better IMO).
