Hope it turns out that she easily beats him at swordsmanship, making her (unknowingly) a prodigy
I would be fine if she was on par with him or just a little bit weaker but I have a feeling he'll pretend to be weak in front of her and she'll be suuuper weak compared to him.
Later, she'll be sad and depressed when she finds out he's not the weakling she assumed him to be...yada yada... Danger kidnapping...yada yada... Reunite marriage
You know something like that
I would love to be proven wrong though
