An engagement broken off at a ball.

It was supposed to be a cliche scene condemning a villainess...

In the middle of a ball, Second Prince Kyle unreasonably announces that he is canceling his engagement to Scarlet, a duke's daughter. Furthermore, he announces that he has a new fiancée, and they make baseless accusations against Scarlet. Scarlet had endured years of torment from Kyle ever since they were young, all for the sake of their engagement, but she could hold back no longer...

"This is my final request. May I send this stupid bitch flying?"

The fair duchess Scarlet clenches her fist and dances!
