The Villainess Is Shy In Receiving Affection

I am Melody who was imprisoned with my wicked mother for pestering the missing daughter of the Duke in the previous life.
We had another chance to switch our fate when my mum brought that girl home, back to the right time. I would take care of her with kindness and warmth.

Therefore, Loretta, the Duke’s hidden daughter spent her childhood with my family, became obsessed with me, who just treated her nicely with the hope of leading a peaceful life.
While following her back to the Duke’s family, she remarked her keeping close to me.

“I hope Melody marries Loretta!”
How would I escape the girl who is a “Fool for Melody?”
