I also prefer riley but question is what kind of endings dev want?
We aleardy know riley fck everything she see and have a dick attach...to remain loyal to protagonist she need to fall in love first and slowly change, if is to quick is not believable...I think the right word is reverse corruption.
Femdom it's not my cup of tea to be honest, but they can match riley is small and mc have small penis with some technic it's possible to win riley heart. He train all days for this no? =))
But if that's happen it's not netorare route, maybe netori?
"Just wish sometimes that the protagonist wasn't such a pussy" is just confuse or blunt is the right word and he have just some hints of mia cheating when he discover the true nature of mia, he can also decide to take riley for him, but only if the dev plan to have also netori route.
But I would like to see more netorare and mystery, discretion sex elements hehehehe
maybe humiliation on final no need to hide anymore and have sex in front of mc. More humiliation both mia and riley have sex in front of mc. sry i'm to sadist hahahaha
=)))
