I think it's less a romance thing and more a respect thing. The best thing you can do for anyone is act in a way that's respectful. And sometimes that's knowing someone's current boundaries. Or it's knowing that you'll be able to handle it if they're not ready for that yet.

[Hunk's mostly seen romance played out over nice meals or quiet moments. He also saw a lot of 'lonely pining guy sticking his foot in his mouth repeatedly rather than talking things out'.]

Do respectful first. Then romantic.
