Just curious, is there any pairing that is monogamous in here? Or NO ONE believes in monogamy?

I mean, I know IC-ly there are characters who *omg love each other*, and most people actually keep a lover to just screw their lover. Yet, I don't see that here?

I know oocly this is a game for characters randomly screw others, but I'm talking about IC. Would all characters icly refuse monogamy even if they have someone they love deeply?
