A few days ago I had an idea a bit like
>>1891852The story is that, after a (failed) assassination attempt in a nearby kingdom, the king increases security in the castle, this includes his daughter getting a bodyguard, a female one.
After a bit of unknowingly requited feelings one of them lets it slip to the other and they both confess to one another, then some light drama/angst over "oh but it is forbidden love, we must keep it a secret", leading to a number of capers to keep it secret.
Eventually however they are found out and, instead of the king finding out from a third party, the princess decides to spill the beans personally, she launches into a long speech, about how she loved the bodyguard, how she takes all blame, that the bodyguard shouldn't be punished, etc.
The king just laughs.
He laughs a long hearty guffaw.
Then he explains that he was aware of her proclivities, or at least had a feeling she lent that way, and actually set up the bodyguard to both test his hypothesis and set up his daughter with a lover. He then explains that as long as she is relatively discreet he has absolutely no problems with it. He then goes on to mention marriage, for multiple reasons (some legal, some diplomatic) the princess and the bodyguard can't be wed (which the princess doesn't like) but he then points out that if/when she is wed it would be a purely diplomatic thing, she is free to do as she wishes in her bedchamber, then lets slip that is the case with him and the queen (there is at least one joke about "so that's why there are so many clumsy maids") and that he would do everything in his power to find the right suitor, even if it is not the most advantageous marriage.
The princess poutily agrees.
If there where to be a sequel/next season/whatever it would probably be them searching for a good suitor, which will probably be a dude in a similar predicament and they agree to be mutual beards.
