Melusha, the protagonist, is an ordinary lady attending a noble academy and engaged to someone. However… A self-proclaimed heroine suddenly appears and forces her to bully her, saying, "I want to win over your fiancé, so bully me!" If she refuses, she threatens to harm her beloved cat. From that day on, Melusha becomes an impromptu villainous lady, bullying the heroine as instructed, always watching the heroine's expression. "Laughing maniacally is so embarrassing… but for my cat, I'll do my best to bully… My stomach hurts." Her fiancé is head-over-heels for the heroine. She has no friends; her only companions are her cat and a priest… Melusha's youth is a mess. As the final event, the graduation party approaches, the heroine becomes more tyrannical. However, someone has been quietly watching over this villainous lady… (A short, easy-to-read story. The cat is never mistreated. Please rest assured.)
