In short, you have reincarnated into the old world

And as it seems that princess you reincarnated into is being bullied by the rest of the nobles and her family, she even had a fiance who was forced to be with her and that guy wasn't into you either.

And now, at a party, a princess from an aristocratic family mockingly pours her wine on your head, and by their bad luck, your character was a savage

So, regardless of the authority of a princess who was engaged to a duke, you punched the girl in the face

"Remember, you started it yourself first" you said sarcastically and made that girl completely defenseless and crying with multiple blows.

And while you were retaliating against that girl, you felt someone looking at you from behind, and you turned around and saw Phytos, the Duke who was your forced fiancé.

Phytos looked surprised, he almost didn't expect the stupid defenseless girl who was his betrothed to even know how to speak.
