Duran

There was someone in the emperor's room who was lying in the gold platted luxury bed with the silk white bed cover on the top of it. Then... it was used by the name as Duran, to recuperate himself. 

He was looked sick with many sweats being visibly seen... Another one who had cast the magic was the one who Kuso always knows...

"Duran... Are you okay? You are abnormally sweating!" The king questioned the prime minister who had fallen sick in his bed in a worried tone. And the girl requested to the king,

"Mind leaving this room first? My lord. Lord Duran had to..."

"It's fine. I have only this son. Even if he had to die, then let me die first. There is no way that a son left his father first!"
