Comments of chapter undefined of Fate's Little Feral Consort

Is everyone else stupid? Why can't they see that the sister is such a "model" person that it literally HAS to be fake? What normal person in normal circumstances has to be persuaded for hours upon hours to marry the guy they profess to be madly in love with? Doesn't that scream "something isn't right here"? I want to slap them. Just a little, just around the edges and maybe the facial region.
