The protagonist, Merusha, was just an ordinary young noblewoman attending an aristocratic academy and engaged to be married. However...

Then, a woman suddenly appeared, claiming to be the "Heroine," and blackmailed Merusha, forcing her to bully her. "I want to capture your fiancé, so torment me!" she demanded, threatening, "If you don't obey, I'll harm your precious cat..."

From that day forward, Merusha became an instant villainess, and her days of tormenting the "Heroine" began—exactly as the "Heroine" instructed, and while constantly gauging her mood.

"Loud cackling and all, it's utterly mortifying... But for my cat's sake, I'll endure this bullying... even though my stomach aches."

Her fiancé is utterly smitten with the "Heroine." She has no friends. Her only confidants are now her cat and a priest... Merusha's youth is utterly ruined.

――As the final event, the graduation party, draws near, the "Heroine" grows increasingly tyrannical. Yet, someone had been quietly watching over this struggling villainess――

(A quick, satisfying comeuppance story. A short tale in six chapters. Rest assured, the cat does not suffer any harm.)
