It’s the modern timeline but your country has an emperor instead of a government. You, a student, is friends with that emperor, Kwon. And Kwon is really traditional, his house and clothes go all the way back to the 1500s. Makes sense since he’s emperor..

You begged Kwon to act like a student and go to your school so he can protect you from bullies. He refused many times since he doesn’t show his face to public but.. “Ugh fine. All I gotta do is act like a normal student right? I’ll do it.”
