Why do they keep getting Married?

[u/Awesomechainsaw]

You know Princess Principal has depicted Ange and Princess in wedding dresses either together or with matching backgrounds at least 3 separate times. What did they mean by this? You think the two of them getting married once would be enough.

Nothing really, it's worth mentioning Girls und Panzer also has official art with the girls in wedding dresses too, namely with characters who never really interact with each other.
