Ironically given what the actual fate of 'magical girls' represents in the mahou puella verse and the relation between the representation of despair(bad end kingdom) of the bad end precure, this is most likely how the puella magi would end up if they existed in the pretty cure verse.
Now that I know how Peach really feels about Mario, I can tell you what she's thinking right here.
"God, you really are a fat, ugly one. Impressive that you defeated the Koopa King, but Bowser was way, way hotter than you. Still, provided you keep your hands off my body and you stay away (far away) from my bedchambers, you may be a source of utility and amusement to me. And to my real man, of course."
