In a world of elegance, a lady with a uniquely sharp tongue appears.
"…Wait, did I just die?" I open my eyes to see a dazzling chandelier. A massive mansion. Dresses. Nobles. The Crown Prince. And the first thing out of my mouth: "...Ah, I'm f*cked." Grace? Dignity? I don't know about any of that. Shouldn't I just focus on surviving first? A foul-mouthed modern girl and the nobility. ...What a mess.

"My life was definitely ordinary." Going to school. Chatting with friends. Swearing a little. I just lived like that.
Nobles. The Imperial Palace. Balls. ...And people who value dignity more than their own lives. Sure, fine. Let's just call it a damn common romance fantasy isekai.
The problem is. That a foul-mouthed person like me is the one who got isekai'd.
