>F Cup
I wish more series got proper bust size and cup size.
Bust declaration is a fetish, therefore it should be true and accurate.

Picrel is definitely bigger than F. Idk what's the author thinking. I assume it's because this is adapted from LN and the girls are way smaller in the original.
The manga artist doubled their size because of his fetish, but he can't stray much from the original narrative or something.
