imo "mom" is more of a problem than "dad".
SPOILERS and ranting ahead.
At least he has his justifications - dragons he hate after Bezriche's betrayal (when she told him she never loved him and disappeared into the air) came and left him some random kid. A kid he is thinking can't be his, because dragons can have kids only with the one they love. No note, no nothing. His emotions are locked (after betrayal, again), he lives by logic, not by heart.
At least Diamid didn't throw her away and let her live in his magic tower despite thinking that she might be a spy from dragon clan. ┑(￣Д ￣)┍
And Bezriche left while emotionally hurting Diamid instead of telling him that they will have a kid together but she was cursed and will die soon, so he will have to raise their kid alone. She left her daughter with dragons, knowing how deeply they hate half-breeds and how hard her daughter's life will be.
Her mom... In a sense, is quite selfish isn't it?
I’m so sick of this “dad” I need there to be a HEAVY redemption arc for him like dead ass life changing cause if she just straight up forgives him I’m gonna be so pissed.
