I, the Wicked Woman of High Society: The Charming Marquis's Son Broke My Arm, so I'm Making Him Take Responsibility

I've always been good at reading the room. That's why I'm now the villainess... so that my sister Marin can be the tragic heroine. If I do not accomplish such, Marin will have father take away my food. At today's event, the young lord of the Balgoa Marquisate, Rio, is in attendance. Of course, I know to throw wine on her dress just as she asked of me. I must make throw everyone into a fuss... at least that's how I thought things were going to go, but the young lord of Balgoa grabbed me by the wrist and suddenly- a snap. Thus began a dramatic meeting one could call a sort of destiny. (Source: MangaPlaza)
