It's funny that there are so many mixed feelings about the princess. If that were an ugly fat dude there would be zero forgiveness. Add a rack, lose 200 pounds, and buy all your clothes from Ho-mart, and all of the sudden almost anything can be forgiven.
Now I have not read the WN, so I have no idea what really happens, but if the princess is under mind control or some other threat that is making her work the slave class to death, then I guess I might be forgiving those tits too.
