Kim (may I call you Kim?) is a kid who struck it rich as an accident of birth. He also, unlike his countrymen, doesn't look like he has missed a meal. Beware of fat little kids who wear generals uniforms and are in line to be king because daddy wants it.
Reflecting on the virtues of a democratic republic, one thing we have going is that except for a recent disaster of father-son, we don't do the king thing. Good lord, there are some who support nitwits that's for sure, but generally we don't care much who is what as long as they might be capable of doing something in the public interest. Clearly North Korea isn't so burdened by the consideration of competence.
Who knows. The kid-king-designate might break the mold but I sure wouldn't bet on it. Nope.
