"Jang Ki-yong and Ahn Eun-jin have the kind of chemistry that makes you forget the plot is falling apart around them — and for most of this drama, that is enough."
A rom-com that burns brightest in its first half — and coasts on sheer charm the rest of the way
Dynamite Kiss opens like a drama that knows exactly what it is and is completely at peace with it. A surprise kiss in Jeju. A fake married identity. A baby products company with an inconveniently attractive team leader. It is shameless in the best possible way — a full-throttle romantic comedy that leads with charm and dares you not to get swept up. For the first seven or eight episodes, it works beautifully. The second half is messier, the plot becomes increasingly strained, and the finale leans on coincidences that would embarrass a soap opera. And yet. Jang Ki-yong and Ahn Eun-jin have such genuine, electric chemistry that even the wobblier stretches of Dynamite Kiss remain compulsively watchable.
The Synopsis
Go Da-rim (Ahn Eun-jin) is a single woman carrying her family’s debt and her mother’s medical bills on her back. When she discovers that a baby products company is hiring married mothers at a premium, she does what any desperate and resourceful person might do: she lies. Invents a husband, invents a child, and walks into the interview with the confidence of someone who has nothing left to lose. The company’s Mother TF team leader, Gong Ji-hyeok (Jang Ki-yong), is sharp, controlled, and deeply unimpressed by people who waste his time. He is also the man Go Da-rim kissed impulsively during a chance encounter in Jeju, before disappearing without explanation.
The drama that follows is built on the gap between what each of them knows and what the other is hiding. Ji-hyeok thinks he got entangled with a married woman. Da-rim is terrified of being found out. Both are trying to stay professional. Neither is succeeding. Kim Sun-woo (Kim Moo-jun) circles the edges of the story as a second lead whose feelings complicate things further, while Yoo Ha-young (Woo Da-vi) rounds out the quartet with a warmth the show uses well in the earlier episodes.
The Cast
Jang Ki-yong (Gong Ji-hyeok): He is doing exactly what this kind of drama needs from its male lead — playing the controlled, slightly intimidating team leader with just enough warmth underneath to make you root for the crack to appear. Ji-hyeok is not a revolutionary K-drama hero. He is a well-executed version of a familiar type, and Jang Ki-yong brings enough presence and dry comedic timing to make the character consistently enjoyable. The scenes where his composure slips are the best in the drama.
Ahn Eun-jin (Go Da-rim): She is the reason this drama works as well as it does. Go Da-rim could easily tip into exhausting — a character who lies constantly and keeps getting away with it — but Ahn Eun-jin plays her with such a grounded, likeable desperation that you never stop rooting for her. There is a physicality to how she plays the comedy that is genuinely funny without being cartoonish, and her emotional scenes in the back half land harder than the script probably deserves.
Kim Moo-jun (Kim Sun-woo): The second male lead is given more dimension than the role strictly requires, and Kim Moo-jun handles it with a quiet generosity that makes Sun-woo one of the more likeable second leads in recent SBS rom-coms. He never tries to steal scenes he is not meant to win, which is a kind of acting discipline that is easy to underestimate.
Woo Da-vi (Yoo Ha-young): Warm, funny, and used well in the first half. Like several supporting characters, she fades into the background as the plot tightens in the later episodes, which is one of the drama’s recurring structural weaknesses.
When It Sparks
The first half of Dynamite Kiss is genuinely good romantic comedy television. The premise is set up with clarity and speed, the misunderstandings are built on actual dramatic irony rather than lazy contrivance, and the chemistry between the two leads ignites early and stays hot. The Jeju flashback structure — the drama returns to that first encounter repeatedly across the early episodes, revealing a little more each time — is handled with more craft than the genre usually bothers with. The workplace setting gives the show a consistent comic engine, and the scenes where Ji-hyeok and Da-rim have to maintain professionalism while clearly failing at it are exactly what this kind of drama should be doing.
The soundtrack is also worth mentioning. For a drama that leans this heavily into its romantic mood, the music earns its place — warm without being cloying, well-matched to the pacing of each scene.
Where the Fuse Burns Out
Around episode seven, Dynamite Kiss starts throwing things at the wall. Loan sharks. A kidnapping. A fire. Memory loss in the finale. These are not inherently bad K-drama ingredients — the genre has made great use of all of them — but here they arrive in rapid succession without the groundwork to make them feel earned. The misunderstanding that drives the central conflict, which was charming when it had an expiry date attached, begins to feel strained the longer the drama stretches it. Characters who were well-established in the first half disappear or get sidelined. The plotting becomes repetitive in ways that the performances can only partially disguise.
The finale in particular tries to do too much in too little time, and the memory-loss arc — introduced late and resolved quickly — is the kind of decision that reads like a last resort rather than a plan. It is not the ending this drama deserved, and most viewers will feel the gap between what Dynamite Kiss promised in its opening episodes and what it actually delivered by its close.
Final Thoughts
Dynamite Kiss is the kind of drama that rewards you for watching it in the moment rather than thinking too hard about it afterward. Ahn Eun-jin is wonderful. Jang Ki-yong is exactly what the role needs. The first half is some of the most enjoyable romantic comedy television SBS produced in 2025. The second half is a different story — messier, more reliant on plot mechanics than on the character work that made the opening so good. An 8 feels right: high enough to recommend without hesitation, honest enough to acknowledge that this drama was better when it trusted its leads over its plot. Watch it for the chemistry. Stay for Ahn Eun-jin. Forgive the finale.
