Well... This is not exactly a masterpiece of sorts, nor it has any element of interest; unless you pick it up to stimulate personal passions... Passions that by themselves have no merit: A honourable man of delights will not build a monument to his obsession and call it virtue upon it being convenient. There's nothing more absurd than a perv that thinks he's using his mind, when in truth he's using his lower entrails.
I say this as someone that associated the era imagery of the cover with that the genre of classic eroguro. If on the verge of being unethical, don't add to it being a dumb bastard that finds entertainment in suggesting clever adjustments that are nothing but inconveniences.
Many an idiot making this the ground meant for the victory of their quarreling side. Moreover, read the air, this is more than likely plain shoujo, by women and for women. I'm off.
