Yeah, getting married is a formality. They've been arguing like a married couple since the start.
A wise woman once told me that you don't actually have to be old or married in order to be an old married couple. You do have to be a couple, tho, if only of the idiot variety.
That was so cute! Rare to see in manga a dynamic like this in high school and move smoothly into college (and after?). Usually managing to get together by high school is the big win (or else there's a timeskip into their adult life).
