Technically the only person who polygamy is legal to is the Emperor of Japan, but after Emperor Hirohito the bastard there hasn't been an emperor who has more than one wife as it's now look down upon along with the letting the attendees raise the children of the royal family, but rather the emperor and empress themselves raising their children...like you know a regular family.
Don't worry; its only the first day of the festival! She can still make a comeback D0=!! Tadano already promised he'd go with her. It'll be her chance to strike!
Gotta also keep in mind that Tadano, and everyone else sans Manbagi, can still think of what she said as her acting. Nothing is going to change.
