The best part about series like this is that it exposes how easily upset people get by huge tits, to the point of coming onto something they don't like just to complain about it incessantly.
If you shrunk the boobs down to be """""realistic""""" size you wouldn't complain as much? Is that really just how vapid your opinions are?
If they were full on lolis/chopping-boards/"THICC"/any combination of those you would probably be praising this series, but alas seeing "unrealistic" boobies portrayed in an unrealistic medium like manga/anime is enough to get some people very, very mad and one-sidedly trash on a series.
It seems only this exaggerated body feature gets this kind of hate.
