I like this story. It makes me think how that "Cake Wedding" fic by Borin23 should have gone instead of how it ended. I had thought that the fic in question would have ended with Mirajane interrupting the "wedding" and saving Erza from the store owner and the pervert she was being married off too, and Mirajane would confess her love to Erza, somehow absorb some of the fat Erza had into herself, and they would date a bit before getting married to each other.
