The villainess reincarnated as a commoner in another world

I am Mathilde von Donnersmack, the fiancée of the crown prince from Northrealm... Or so I was until he declared his intention on making a commoner girl into his fiancée, and sent me on exile under the accusations of harassing the commoner girl. Then before I could notice I was being run over by a merchant's wagon, only to wake up at a cold and bright place full of people wearing light blue... Yes, I was reincarnated in another world as a commoner girl named Kimiko Uehara, in a nation called Japan, that has amazing wonders such as anime and manga, but now I shall first reclaim my original stature as a noble!... Eh? What do you mean there's no such thing as magic?... Ouch! Why did you hit me!? Huh? That's not how I ask people?... What do you mean by calling me a weirdo!?!?!? TL;DR: Simply put, it's the reverse uno card to the reincarnated as an otome-game villainess, where the villainess reincarnates as a common Japanese girl Cover* source: 03_Bara_ [Twitter] *Between the ones I had, I found it the most fitting for what I'm "thinking" for this story
