tbh bertia and katarina are both lovable goofs but operates in different plotwaves, bertia has the OP love ones and katarina has herself as the plot twist despite all the efforts her loved ones has... or at least that's the result of my layman analysis brain lmao
but in this case, it's a holy mix between the two, it's just bertia is much more adorbs(subjective ofc) hence bertia vibes lmao
