I think one of the things I enjoy about the series is that their antagonism is purely performative. The best moments of the story are when they are doing their back and forth and one of them stops and says, "do you really hate me? pout tears" and the other is like, "Oh no baby, I love you so much."
For a dragon supposed to be above all, she REALLY enjoys being conquered(hidden dragon kink). Often. Once Leon figures out how to become the world's best dragon layer. Their power dynamic on these early chapters is a bit uneven, but once he levels it out it becomes a lot more fair and different and you get to see them be more honest.
