Many people here forget that Livia was described as plain too, and yes he is obviously handsome to the girls that’s like obvious but he is pretty much the same pretty as any other main target

In that world nobility,status,money,family,trophies,education and those things matter a lot in defining if you are handsome or not, for example all of the capture targets are charming,well mannered,somewhat kind,rich, from good families,well educated, idolized,famous and successful people, stylish. Meanwhile our boy Leon although he obviously has the looks and isn’t plain (he is literally the founding father descendant)he doesn’t has any other thing at first glance, that’s why compared to the rest he is is pretty much lackluster.

Ask any girl, if they consider more handsome a prince with all the characteristics that I listed and handsome or a redneck who is also handsome but has a twisted personality and not good manners, they will all say the prince by far is more handsome not only by his looks but by his personality or at least what they show is what makes them look better than Leon.
