They couldn't be more different. Ridley is a knight in shining white armor, so perfect in every way that it makes people hardly able to stand him. Prince Vandel on the other hand (aka the evil demon prince of darkness) is the sworn enemy of the kingdom, obsessed with gaining power and wearing beautiful clothes. The two young men are right out of a fairytale, practically made to be archenemies...but what if they ended up falling in love instead?

Levi wasn't the kind of guy to go around kissing strangers, least of all the insufferable princes these events tended to attract. But something about Prince Charles made him feel a little stupid -- almost stupid enough to believe in love at first sight. ~~~ When Levi, the youngest prince of Arthur Island, is forced by his parents to attend a performative "good relations" ball in their rival country, he can't wait for the night to end. That is, until he meets Prince Charles, the charming heir to the Elizabethan throne. Love is in the air, so palpable they can't seem to escape it no matter how hard they try. As if navigating seventeen-year-old emotions isn't hard enough already, their families drop a bomb that will only make it harder: In the name of permanent peace, Prince Charles is to marry Arthur's youngest royal. No, not Levi. His twin sister, Amelia.

In which, a knight watches the person he loved, fall for someone else. That too, after a single dance.
