Do you know?

Denis and Harris were once enemies in the first book, The Universe Beyond Ours, and they became best friends amidst the story. Now, let's consider this book, A Bridge Between Two Realms. We can categorize Denis and Harris' relationship trope as "enemies-to-friends-to-lovers" or, in short, "enemies-to-lovers" trope.

Well then! Above is a quick sketch of their relationship development in the first book. I hope you, my dear readers, enjoy the art!
