The king is sufficiently naïve and puppy-like that I can imagine him getting enough character growth to become genuinely likable, and can almost imagine him becoming a viable romantic partner, although it seems like it would almost be more like raising a kid than dating someone...
I want to give him some credit in that everyone else around him seems to think that his selfishness is appropriate behaviour for his station; you can't really say that his being a complete brat is his own fault.
Well, accordingly, whether this is good or not, time will tell, I guess.
