Ok, this is rollercoastering pretty hard, but at least I can kind of understand where they're both coming from.
Also, it's hilariously funny that it was the character who was supposed to be the heroine that actually paved the way for possibly clearing up the misunderstanding here. I'd laugh my head off if she's actually just someone playing the game and happened to unlock a secret ending where she takes over her father's estate instead of marrying the prince.
And the prince's knights/retainers are always entertaining.
