No
They know that she's an orphan that's why those 2 ml didn't like her coz they feel like Penelope is taking the place of the real daughter (that they are taken advantage of) plus the fl is reincarnated as the villainess in the game she played in her previous life
Oh.
If you're asking about her transmigration, then no. They don't know that she's had a soul switch with someone that's from another world.
But if you're asking about her biological relation to the Duke, then yes. They know she's not the Duke's real daughter.
thanks i only forgot if they knew that
it was if she was the biological daughter, thanks
i don't remember the beggining bcs i read a lit of those manhwa's, does her family know that she's not the real daughter?(not the real penelope, the real daughter)
