Is it just me or pages 5-6 should be the first ones, 'cuz it make no sense to begin with the dating stuff and go back to where they left of last chapter.
I think 5-6 are flashbacks to the beginning of the date, after things are in full swing. Note the last panel is dark, leading into the next page which is also in the evening. It's a little awkward, but it works when you realize that.
