Honestly based on this I’m gonna make a guess that…
Dude with the black hair is her real father based on the questions he asked her like if she’s the only one as if he was wanting to know if she has blood siblings aka more of his own kin.
That's honestly what I'm also speculating. But there's no discussions on the novel about that, like nothing at all. So I think.... maybe? He's not a candidate? Idk.
Yeah I was think that since the moment she said “I’ve never met my father before” bro dipped like a deadbeat father would do in these stories lol.
I got so impatient and searched for some spoilers lol. Don't read the rest if u don't wanna be spoiled. This is just a bit though. Nothing grand ig.
Valer (Valar in the novel) is not MC's Father. He's her uncle. Younger brother of MC's Mother. Her mother was impregnated by non-human, like a higher enitity or smth. Unfortunately, it seems that there're still no update onto who's her father. There are discussions that the Mother was raped, but nothing is sure yet.
