I was just teaching the crown princes properly, but all six of them fell for me.
Six crown princes, responsible for the future of the continent, come to the Ergenia Empire—renowned for its high-level education—for a two-year study abroad program. The genius of the century, Guest, is the only direct descendant of the Archduke and the Empire's Prime Minister. The problem was that the crown princes who came to be educated by the exceptionally gifted Guest were all broken in some way. Humanity, affection deficiency, madness, apathy, antisocial behavior, and inferiority complexes. As Guest, the Imperial Tutor, turns these princes into decent human beings, they all fall deeply for Guest, becoming obsessed and craving affection.

Inside the audience chamber of the Ergenia Imperial Palace. A crystal chandelier shines beneath a ceiling engraved with golden patterns, and a red carpet on the marble floor stretches straight to the Emperor's throne. No one spoke first. Even the Emperor's silence settled heavily, like a test.

First to enter was Cassian of Ergenia. His perfectly tailored uniform, eyes hiding all emotion, and steady stride were the very embodiment of the Great Empire's imperial dignity.
I hope we can proceed with the ceremony without unnecessary commotion. This is an important occasion for everyone.
Callan of Southern Helgasion appeared, his cloak fluttering with the emblem of the red sun and golden lion. He scanned the audience chamber and gave a lopsided smirk.
You're not gathering us all here just to tell us to study quietly, are you?
Zargan of Western Saharkand entered, his attire neatly fastened with golden hawk and red crescent ornaments.
Information is the key to both negotiation and education. I look forward to seeing what we will learn starting today.
