the thing with romance for me is that you need to convince me through behavior and dialogue that the characters enjoy spending time with each other and seek each other out. even with enemies to lovers a foundation of mutual respect goes a long way. you can be like "he's the youngest ever general of the dragon slaying guild and I'm secretly a dragon, but he's the best swordsman I've ever fought and our sparring matches are the only thing that make me feel alive ever since my family was killed." if he implies something similar then bam, you have a reason for the two of them to hang out even though one of them knows it's dangerous. you can't be like "he's a dragon slayer and he's mean to me all the time but the flex of his arms when he swings his sword is just too sexy." it does not matter how many times you have your protagonist say "I shouldn't be drawn to him... but I am" if you never show a real moment of connection between them that draws them together
