I know they aren't supposed to be, but lol no matter how you look at it, those porn magazine girls look way too similar to the real Jindou and Ayumi. I mean literally the only difference in Ayumi's look-a-like is the placement of the ponytails. Everything else, even the scrunchies and the eyes are the same lol. Fortunately, there's way too much going on plot-wise for NTR to make sense in this manga lol.
