The Villainess Is Shy in Receiving Affection

My wicked mother brought a girl one day, the Duke's lost daughter, Loretta - the heroine of a novel called The Duke's Four Children. And I am Melody, the villainess in said novel who was punished alongside my mother for harassing the Duke's precious little girl. I didn’t want to die like that, so I decided to treat her well. I fed Loretta, put her to sleep, and played with her. And then her response was…?

"I hope Melody marries Loretta!"

Through her endless affection, I ended up coming back with her to the Duke's mansion, where she said "I'll stick close to Melody!"

Has there ever been anyone who is such a 'fool for Melody?!' Why am I being loved when I've only been kind to be able to live peacefully…!
