Their Fated Magic

The chemistry between the characters felt so natural, but I'm curious what inspired the decision to set their rivalry within a fantasy world full of magic and danger.

The tension kept me hooked, but I kept wondering if I was supposed to sympathize more with one side. How do others feel about the enemies-to-lovers dynamic in this context?

The way magic influences destiny felt so integral to the story. I'm curious whether the author mapped out the magic system early or let it evolve during writing.
