I mean, I personally think it can be significant when two apparently unrelated characters seem to have p much the same hair colour, from what I've seen, especially when there's already been so much foreshadowing/implication on there being a nobleman who played around with Carla 20 years ago, which is Anna's age... for example, in a panel where we see the nobleman depicted playing around with multiple village girls, one of them is very likely Carla, considering the hairstyle was the exact same (colour + style). I think it'd be very funny if Anna and Franz turned out to be half-siblings.
I think the gentleman that came to the village 20years ago was that kblond knights dad or a family member and the mum had a thing w him and by the time she found out she was pregnant blonde player was gone so she married her now dead husband to cover up the pregnancy so people don’t talk. Cuz even the mum said that their FL doesn’t look like either of em so I think she just looks like the knight in my opinion.
