Would be pretty unbelievable, since, for right now anyway, they are stock types and not characters. Nearly every NTR game has a fat old guy in power and/or the black male rapist type. As I said, it's there to include popular elements from other games, not to create compelling characters (at least, at the game's inception, I know they are not your creations.) They exist to grab a demographic, I don't recall them in the first update so it's possible they were included at patreon's requests, I'm not sure. Can you see why time devoted to them rather than the well-written characters might feel vexing?
It might actually be interesting to have a game where there's a rival who is an interesting, well developed character and is likable. NTR fans might appreciate not getting the same stock character types. I think their models might have appeared in the same roles in a few other games, too.
