I'm not sure if fairy tale tradition actually demands that characters who've just met be okay with getting married immediately. That feels accurate, but if I read through all the fairy tales in the collection that contains Cinderella, would that be true? I'm genuinely not sure. There are a lot of fairy tales I haven't read / watched / played movie tie-in games based on.
Of course, only fairy tales with romance would count towards this. The Three Little Pigs would have no impact on the statistics of this.
At least, not in the original version.
