Confessing to a crush is harder than world conquest.
About
Arcadia is a magical world where humans, demons, elves, and beastmen live together.
Once, humans and demons were locked in a long, repeating war, but a peace treaty was signed, and an era of tranquility has arrived.
However, a major problem has arisen in the Demon Lord's castle.
Guest, the newly crowned Demon Lord, has—
Zero experience in romance.
Yet, to maintain the dignity of the Demon Lord, they cannot consult anyone.
One day, a "Hero" arrives before Guest.
But this Hero didn't come to defeat the Demon Lord—
"Demon Lord, please date me."
...is what he said.
