YMMV / The King: Eternal Monarch

• Adorkable: King Lee Gon has his moments when it comes to the woman he likes. Just consider his first declaration of love to Jung Tae Eul.
  Lee Gon: Among real numbers, zero is my favorite. You have the nature of that number. Usually, a zero means there is nothing, but it’s actually a number of absolute power. It can nullify any number or take everything away from it. (...) Because of you, I’m powerless here, but it’s fine. You are much more amazing than I had imagined. And you are standing in front of the root symbol I’m trapped in.
• Designated Love Interest: Some viewers felt that while Lee Gon makes it clear he has a huge crush on Jung Tae Eul from the start, Jung Tae Eul's reciprocation comes rather out of left field and oddly, right after she has seen the riches of his royal life.
• Moment of Awesome: Lee Gon coming to the rescue with the entire royal guard, riding a white horse, and shouting "Save her! She's the future Queen of Corea!"
  • Also, Lee Gon and Jo Young walking to stop the coup in the past.
