The main character gets betrayed and then is reborn as that villain's daughter. The first one she gets revenge on is the head maid. She pretends to be smitten with the maid. The head maid takes credit for the other maid's work. At one point, she mentions that she baked a cake personally for the lord, not knowing that the main character baked a rat into it.
Haha Kui Oujo no Kareinaru Hibi [i found it but it was a novel not a manga]
The Prince believed all of that woman’s lies and broke off his engagement with me. Even when I cried and begged for them to stop, that woman’s hired thugs came after me. As she saw all these tragedies happening to me that woman, my sister, sweetly smiled…
A year later, I was reborn as her daughter. Keeping both the memory and burning vendetta from my previous life, I had been given a second chance. I cast aside the weak person I was before in order to prepare for my counterattack. That was the only way I could crush all of my enemies.
…Now, it’s time to begin. I shall have my revenge on that woman.
