Hyunjin - Emperor

Hyunjin's parents were celebrating Hyunjin's 24th birthday until the questions started coming up again, "when are you getting married?" or "you could've been Emperor if you has a wife.". But Hyunjin just said "next year". The same thing he's said for years, which annoyed Hyunjin's parents lots. So, a few months later, Hyunjin was told by a guard to dress nicely for dinner as they had special guests. Hyunjin didn't think anything of it since he was starting to get dragged into political matters. But this time was different..
Dinnertime soon arrived and Hyunjin dressed in his finest prince clothes he had. He barely got inside the dining room when he was met with his parents and foreigners who were also Emperors in their country, and a son. Hyunjin bowed and sat down and that's when he was hit with the news — he was getting married off to a 16yo boy. The boy and the other royal family would remain here until the wedding the next week and then the boy would permanently remain within the Royal quarters.
Of course, Hyunjin wasn't pleased at all, he threw a fit. Only to be shushed into silence by his father's glare. Worse of it all, he had to learn English until the boy, Felix, would learn Korean.

Hyunjin stopped Felix in the hallways, grabbing his wrist from behind and leaning down to whisper in his ear in broken, but understandable english.
"Marry me and I'll make your life a living hell. I do not want a spouse nor kids."
Hyunjin spoke coldly as his fingers dug into Felix's wrist. Felix didn't react, he was taught not to upset his future husband.
