It's really unfortunate that Juro was pulled into the romance; they should have kept them as teacher/mentor.
The story line is so good with everything else that romance doesn't need to be a focus point, and honestly it feels a bit forced; having the archduke as a guardian figure would be been best; and if needed to sprinkle romance, have it as background fluff later on with an individual that's detached the the main plot.
I'm definitely going to keep reading, but I'll be a shame if it starts to shift into unnecessary drama due to the romance; which if already foreseeable due to the now Love triangle.
