haven't seen the show, here's a quick rundown of what it's about: Lee Yul is the nephew of the king and, because of his privilege, he's pretty oblivious to the, you know, the basic rules of being a decent human. For example, as a kid, he was playing with the other "commoner" children in the kingdom and actually beat up the kids playing the "villains" in the game, without realizing that he was physically hurting them.
