PrePub - Ascendance of a Bookworm

I'd say Hannelore is indeed quite equal to Rozemyne in matters of romance, i.e. very perceptive in romantic matters concerning others, but almost entirely blind to their own. Just like Rozemyne, Hannelore needed someone else to open her eyes to what was going on.

And to be fair to Rozemyne, she is far less familiar with noble romance, since when she should have been taught, she was in a coma and afterwards both her noble mothers assumed the other one would do it, leaving her hanging. And Ferdinand is a master in masking his emotions, not to mention rather inexperienced in romantic matters himself and only having come around to making outright advances pretty much during the war.

Meanwhile Hannelore was taught well, understands the noble euphemisms around love and had her romantic prospective partners either mess up and show their feelings openly by mistake (i.e. Ortwin's blunder) or just state them straight up like Rasantark, with either little or no room for misinterpretations.
