Context: Main character (crown pince) uses disguise magic to come across as sickly so that he doesn't have to marry a noble lady. His plan is to get the noble ladies to fall for his fit, handsome younger brother and to make him the emperor since he doesn't want to become one and just live a chill life. Yes, he is a descendant of Lloyd from The Greatest Estate Developer with less crazy facial expressions but the same exploitation work mentality.
