Viewing this clip, I am reminded of other musicals where the future relationship between characters is 'foreshadowed' in a song ('Only Make Believe' from Showboat, 'If I Loved You' from Carousel, etc.) It's obvious that there's a romantic attraction, but it's too early in the film/show or the 'slow burn' is intentional for dramatic effect when the relationship is finally allowed to bloom. These two are obviously 'into' each other, or at the least, very intrigued by that notion. The flirtatious banter and eye contact are impossible to ignore.
