That's unlikely. The pattern about this curse is that the person they dream about liked them/somewhat liked them/were natural but open to liking them but an unfortunate event happens and they start hating.
We see that with the first ancestor couple
We see it with his mother
And we see it with him.
Oohhhhh
In the mother's case we see that the king at first Didn't actually hate her. And It's even hinted he might have actually liked her! But after the king's younger brother- who was just a child, died due to ML's grandfather( aka the mother's dad lol) having some hands in it, he started to hate the whole family including the mother.
How did I miss this
What if, she mistook the king as her destiny. What if the 4th prince was the one in her dreams?
