Parallel universe, time travel, PURE UNCONDITIONAL LOVE.

After you watch all 16 episodes, you come to terms with why the actors were the way they were in the earlier episodes. This drama does not follow the typical K drama arc. You have to watch it from the beginning and finish it before you fully witness the character development of each character - esp Lee Gon and Jeong Tae-eul.

From episode 1-13 your mind goes into unlimited theories which may make it appear confusing to most people but after watching episode 14-16, you see how beautiful everything comes together.

So if you made a review without completing the 16 episodes, I think the review isn't valid, because we should take something and evaluate after watching the whole thing to be able to get the writer's vision of the story.

This drama has the best HUGS or EMBRACE in all Kdramas I have watched and I already have been a witness to KGE's acting which improved even better after Goblin but the jump in acting skills is higher for LMH - gone are his boyish ways, this drama was a perfect showcase of his "majesty". I think they both were the perfect cast for this drama. Apart from them, the characters of Jo Yeong, Jo Eun-sop, and Kang Sin-jae were also VERY IMPRESSIVE.
