Reeves' move is referred to as "manner hands" in South Korea:
Compare with, for instance, the way current Presidential candidate Joe Biden touches women.In the West, people are generally mocked online for doing awkward hover hands, but the Korean press seems to applaud the "manner hand" as it's seen as respectful. Women, it seems, appreciate the "nice guy" gesture, while men probably don't give it much thought.
Pretty interesting nugget regarding Korean culture.
