If the devs had desired breast diversity, the obvious candidate would be Hana. Unlike the Carnations or house girls, she wasn't
selected to appeal to the ever-so-slightly superficial standards of the Club, and unlike Mina she isn't a model/actress by profession. Hana is just a girl with a notable father; giving her 50th percentile tits would make sense, and IMHO make her even more attractive. It might make her stand out a bit more from the usual crowd, too, not that she *needs* help in that department.
Veronica would be the next most likely candidate, given her rigorous workout routine, and I could see Kathleen selecting her despite her substandard bust just for the fun of breaking her. Of course given how tall she is, even proportionally small tits on Veronica would still be somewhat on the larger side so it's a bit of a technicality. Kathleen and Dr. Lundgren are probably the next most likely candidates for mammary mitigation. But even here I think the large size it suits their narrative role a little more neatly; no need to waste time wondering if Kathleen has a deep-seated case of boob envy.
At any rate, this is definitely not a complaint - I'm happy with all the girls as they are. My personal taste is a bit different than our devs when it comes to breasts, but the rest of the package more than makes up for it.
