The sheer anger exuding from these comments. Are you people offended by breasts? If so, why dislike a manga where the MC denies dozens of women in spite of their breast advantage? Shouldn't you be championing it instead?
So I can only imagine a few scenarios in which this keeps up like it is. A part of this is that the unknown protag is actually an ass man so all these big boobed girls have lost from the start. Also the guy is really devoted to his girlfriend. He may also be super rich, popular, or handsome.
These aren't so much "attempts to seduce you" as "affirmations that your girlfriend occupies the lowly B-caste, and that the woman in question has a right to claim and possess you due to her superior caste status." Like some kind of bra-size oligarchy.
remember kings, it's the heart that makes the girl not the boobs.
even though the heart lies behind the boobs, one must look past them tiddies, and look at the person for who they are.
