Let me start with a premise: The King: Eternal Monarch is a drama that divides people. It's the kind of series that you either love for its epic romanticism and excesses, or you drop because the plot makes you feel like you're trying to solve a geometry theorem while someone chases you with a sword.
The premise is fantastic. The idea of two parallel worlds — a modern Kingdom of Corea led by Emperor Lee Gon (Lee Min-ho) and the Republic of Korea where detective Jung Tae-eul (Kim Go-eun) lives — is fascinating. The way the story intertwines Gon's childhood trauma, his father's murder, and the mysterious figure who saved his life (with Tae-eul's badge in his pocket) creates an initial mystery that keeps you glued to the screen. Lee Min-ho is perfect in the role: elegant, charismatic, and with that wounded look that makes you understand that behind the crown is a boy who never truly grew up. Kim Go-eun, for her part, gives Tae-eul a solidity and intelligence that make her anything but a passive female protagonist; she's someone who fights, and she does it alongside her man, even if they often find themselves in different dimensions.
The chemistry between the two is the real engine of the drama. If I'm being honest, there were moments when the main plot — with all its talk of time portals, magical flutes, and quantum physics — became so convoluted that I risked losing my way. And that's where they come in: Lee Min-ho and Kim Go-eun have an electric tension that makes even the most absurd scenes believable. The scene where he arrives on horseback, covered in blood, shouting "Save her, she is the Queen of Corea!" is such blatant excess that you can't help but love it. It's pure Korean drama, for better and for worse.
I really appreciated the fact that the story left me wanting to know more: I found myself trying to connect the small details scattered throughout each episode to figure out what would happen next, and that's usually exactly what pushes me to watch a drama to the end. I think there were many plot twists I didn't expect at all and, although some of them didn't fully convince me, I still found them compelling enough to keep watching. For me, it was the plot as a whole that drove the series, more than the characters — if that makes sense. It's as if the story itself were the true protagonist, and the characters were the lenses through which to view it.
Kim Go-eun's acting was extraordinary. I don't think anyone could have done better: she captured the emotions perfectly.
A special mention also goes to Woo Do-hwan: he plays both Jo Yeong, Gon's bodyguard, and Jo Eun-seob, Tae-eul's friend, managing to shift from formal, loyal rigidity to a comic and slightly clumsy sweetness with a naturalness that is a pleasure to watch. For me, he was one of the best surprises of the cast.
The soundtrack was epic. The music created the right atmosphere: whether it was romantic, heartbreaking, happy, or action scenes, the soundtracks accompanied them perfectly.
What didn't fully convince me? After episode 10, the story starts doing acrobatics that sometimes feel gratuitous. There's a final plot twist about who saved Gon as a child that, in my opinion, takes away some of Tae-eul's agency and makes Gon the center of everything, which honestly I didn't feel the need for. Moreover, some secondary characters and subplots (like the Prime Minister's) seem a bit sacrificed or resolved too hastily. The writer uses the "time jump" to give vague explanations and resolve intricate knots, which left a slightly bitter taste in my mouth.
And then we come to the ending, which is the part that left me most with a bitter taste. I have to acknowledge that everyone got their happy ending, but I didn't like the two protagonists' ending very much: they see each other two days a week and travel endlessly through time, without a stable life. I would have preferred a more rewarding conclusion, one that gave them a concrete daily life — in short, a real life together, instead of this eternal commuting between dimensions.
In conclusion: The King: Eternal Monarch is not a perfect drama. If you're looking for rigorous science fiction and a plot without holes, it will probably make you curse. But if you're willing to let yourself go, to enjoy the lavish aesthetics, the over-the-top romantic scenes, and the chemistry between two actors who know how it's done — and if you love intricate plots that push you to look for clues episode after episode — then it's a journey worth taking. It's a drama that asks you to believe in love that crosses worlds, and sometimes, that's all you need. It's just a shame that the ending didn't give me the stability I was hoping for.
