Spoiler!
The king is in love with the Bodyguard ex boyfriend. Geumho when he was going out with the Bodyguard, the king became extremely jealous, surely he told (threatened) them to break up but they never did. So the king beat and raped Geumho to push them to break up. And that had the desired effect: the Bodyguard was afraid for Geumho and broke up with him. Afterwards they separated, each going their separate ways, trying to forget the past. Bodyguard (I forgot his name) was very angry with the king, and they didn't see each other again and the king had to go because at no time did he approach the Bodyguard or Geumho. Surely that's after that that Geumho became a libertine, until he met Beom.
So, facing a king, the Bodyguard was defenseless and helpless. We must not forget that in this manhwa, we are in a time when ranks and social classes were above everything.
