The 1 dislike is from a person who didn't want to humor their "like brother and sister" bit. I mean, though, come on. Despite their act of it, and their words, I really can't take their brother-sister act siriusly. Perhaps if they didn't gaze into each other's eyes every time they spoke, and constantly make each other laugh, and altogether weren't so horrid on hiding their secret marriage. They wear their vows and their rings in each longing look, come on.
