The Villainess is a Cat

I was bound to the Villainess System, but I’m a cat. System: Forget it. Your basic character setup isn’t basic at all. Go seduce the male lead. By day, his expression never changed. “It’s just a cat.” Once no one was around, he crouched in front of me. “Kitty!!!” The System told me I had to leave as his white moonlight, then reappear before him after the male lead got together with the substitute heroine. Now that the three-year deadline had arrived, I rubbed my paws together. Meow, motherfluffer. Let me see what this substitute is all about.
