"A genuinely clever premise that the drama never quite figures out how to use. Choi Si Won is charming; the script is not."
DNA Lover had one of the more original K-drama premises of 2024 and then mostly wasted it.
The concept is genuinely good: a genetic researcher who has been cheated on too many times decides to apply science to the problem of love, screens potential partners for genetic compatibility, and ends up entangled with a charming ob-gyn who is running his own DNA con. DNA Lover aired on TV Chosun from August to October 2024 across 16 episodes and had everything it needed to be a smart, funny romantic comedy. The problem is the execution – a script that introduces interesting ideas and then repeatedly fumbles them, a lead character whose decisions strain credibility even within the drama’s own logic, and a love triangle that never generates the tension it needs to function. Choi Si Won holds most of it together through sheer charisma, but he can only do so much.
The Synopsis
Han So Jin is a genetic researcher who has been burned by one unfaithful boyfriend too many. Armed with the belief that the right genetic profile can predict a compatible partner, she ends her latest relationship and sets out to find her scientific match. She crosses paths with Shim Yeon Woo, an ob-gyn who knows more about genetics than he lets on – and who, for reasons that unfold slowly, decides to present himself as exactly the DNA match she has been looking for. Also circling the situation is Gang Hun, a firefighter and childhood connection. Who So Jin ends up with is not really in question; how the drama gets her there is the problem.
The Cast
Choi Si Won (Shim Yeon Woo): Choi Si Won is the drama’s most reliable element. Yeon Woo is charming in a slightly calculated way – the kind of man who always seems to know exactly what he is doing, which makes the slower emotional reveals more effective when they arrive. Si Won handles the comedic moments well and the heavier backstory material competently, and his screen presence keeps scenes moving even when the writing does not. He deserves a drama that is as interesting as he is in it.
Jung In Sun (Han So Jin): So Jin is a frustrating lead not because Jung In Sun plays her badly but because the script writes her into corners repeatedly and then solves them through coincidence rather than character. Her DNA-logic framing device is the drama’s most interesting idea and it gets progressively sidelined as the episodes go on. Jung In Sun does the emotional scenes sincerely; the character just never gets to be as smart as her job title suggests she should be.
The Gap Between Concept and Execution
The DNA compatibility premise is genuinely fresh for K-drama, and the early episodes use it with some wit – So Jin processing potential partners through genetic screening is a funny and specific character detail. But the drama loses confidence in the idea fairly quickly and falls back on more familiar romantic comedy mechanics: the deception plot, the misunderstanding that separates the leads, the love triangle that does not generate real tension because So Jin’s feelings for the second lead never read as anything other than friendship.
There is also a structural problem midway through, where a key plot twist involving a DNA mix-up derails the main relationship for several episodes based on a logic gap the drama never addresses. So Jin processes the implications of incorrect data without taking the obvious next step of running the correct test – and the drama simply moves on as if no one noticed. It is the kind of writing lapse that breaks the spell of a show built entirely around a researcher who is supposed to be detail-oriented.
Final Thoughts
DNA Lover is watchable, largely because of Choi Si Won, and the premise alone makes it worth a few episodes to see if the concept clicks for you. But at 16 episodes it is longer than its material justifies, the script consistently underdelivers on its own setup, and the ending arrives with relief rather than satisfaction. For fans of Choi Si Won specifically it is worth the time; everyone else can reasonably lower expectations or skip it without much regret.
