Develop your own version

Start by defining one rule of magic that creates an intimate difficulty. Perhaps two enemies can read each other's annotations, or a crown grants authority to someone the palace normally ignores. The rule should offer opportunities as well as costs. Give both leads a reason to challenge the political or magical system, but let them disagree about how. Their attraction then becomes part of the plot rather than a pause between battles. An outline needs visible consequences for using power, concealing information, and breaking promises. Ask what the couple could achieve together that neither could achieve alone, and what they must surrender freely to make that possible. Avoid making magical bonds a substitute for meaningful consent or earned trust. These ideas provide original settings, opening scenes, and ten-beat story structures. You can change the form of magic, the source of authority, or the relationship trope while keeping the emotional question that interests you. Explore enemies to lovers or marriage of convenience for a different way into the same fantasy world.
