I haven't read the novel, just spoilers from novel update. I think camilla will know abt her dad in this part itself coz she will be spending time in this place (where she is and crown prince is rn), she will also meet her younger brother(duke married another woman and has a child with her), he is an adorable lil boy who will like camilla alot and vise versa. This duke of a father wants camilla to come with him, he doesn't care abt ravi but is willing to acknowledge him as his son if thats what will make camilla come with him. From what i read he is not a good character, he left camilla's mom with a newborn camilla and never returned(some say he lost his memories), idk how he realised thats his daughter tho. Anyways overall he is a bad parent, not only for abandoning camilla and ravi but also he didnt know that his youngest son was being abused by the nanny, camilla was the one who revealed it. Ik you didnt ask any of this but i dont have the answer to your question so i just revealed some other stuff
Thats camilla and ravi's dad innit!??? He Literally got ravi's hair and camilla's eyes
