Nineteen stories cover events never seen in the main series, supplying readers with a greater insight into Myne’s attendants, her lower-city family, the nobles of other duchies, and even members of royalty! Spans Parts 2 to 5.
But unlike with Damuel and Brigitte, there at least weren't any boken hears there (other than Tuuli's anyway). And there is a small hope, that with the desperate need to keep her out of the loop now lessened, if not entirely gone, they might still make it work, if Karin were to ever visit Alexandria and happen to run into Benno there.
I'm really torn on this... on one hand in their world it'd be a great match, would get Benno a wife he gets along with well, after the hardships he endured with Liz and would get Karin out of an enviroment in which she's likely stigmatized to at least some degree, in part for potentially being seen as "used goods" and in part due to guilt by association with her father, who cost his duchy quite a bit and was punished accordingly.
But on the other hand Benno is at least 15 years older than her (more than 17 Earth years by the way), which is more than Ferdinand and Rozemyne's 13 years apart, and without the fuzzy factor of Rozemyne's mind being a mix of the child born in this world and a fully grown adult from Earth.
