Help

The FL was the heroine and died multiple times to do some kind of disaster, she was reborn many times to try again and not die, i dont remember how much times she got reborn again, but this one time she got reborned as the villians daugher, her now father is a Demon King, the demons think he betrayed their mind and so on, then the gods who kept bringing her back to life said this was her last chance. She grew to earn her fathers love very quickly because she was cute lol. But since she is in a body of a baby she is very smart, her father sees that she is gifted and bring in a boy from his so called orphanage or camp, where he kept boys and trained them to fight for him. He calls in a boy who supposedly understands non human language. So when the girl talks to him with the baby sound he understands. The FL hates her father because he was the villian in her story, but later comes to love him. I have more to say but i dont want to be too long.

Facts:
Her original self had red hair and a blonde fiance (i think hes evil)
The boy who was brought in has some kind of legendary magic whispering something something.
