Set in 1999 during widespread Y2K doomsday panic, The WONDERfools follows a ragtag group of ordinary residents in Haeseong City who accidentally gain unstable supernatural powers.

They reluctantly join forces with Lee Un-jeong (Cha Eun-woo), a socially distant civil servant from Seoul, who grows increasingly suspicious of the bizarre events unfolding around him.
Together, these misfits must confront a shadowy figure — Dr. Ha Won-do (Son Hyun-joo) — who conceals dangerous intentions behind a composed exterior. With the fate of Haeseong City and the arrival of the new millennium looming, this found family must overcome their own limitations to protect a community they never meant to be part of — whether they want to or not.

🏁 Ending Explained
Full spoilers ahead — everything that happens in the finale and what it all means.
Spoiler Warning — This section covers the full finale of The WONDERfools. Stop here if you haven’t finished the series.
New Year’s Eve becomes the final battlefield. The finale opens with the four misfits standing at the edge of the new millennium they were never supposed to protect. Dr. Ha Won-do’s endgame — harvesting the power of the Child of Eternity to essentially rewrite history and prevent what he sees as an inevitable catastrophe — snaps into sharp focus. The Wunder Kinder, his superpowered enforcers, are dispatched to neutralize Chae-ni before she can interfere. What follows is the most propulsive action sequence the show has delivered: Chae-ni, Gyeong-hun, and Ro-bin deploying their abilities not cleanly or heroically, but messily, creatively, and with the kind of raw stubbornness that defines this entire series.
Un-jeong’s transformation is the emotional core of the ending. He arrives not as a reluctant bystander this time, but as a full participant — and the show makes clear that his choice to stay in Haeseong City is the most significant thing he has done in his life. His power, previously limited and poorly understood, manifests at exactly the right moment. It is the kind of dramatically convenient timing that a lesser show would overplay, but The WONDERfools earns it because the groundwork — eight episodes of reluctant belonging — is already in place. When Un-jeong stands beside Chae-ni for the final confrontation, it does not feel like a plot beat. It feels inevitable.
Grandmother Kim Jeon-bok’s secret is the key to everything. The revelation arrives in the middle of the climax and reframes the entire series: Jeon-bok herself was once connected to the same supernatural lineage that produced the Child of Eternity, and her choice to suppress that power — to live quietly, to protect Chae-ni — is the reason Chae-ni became its vessel. Dr. Ha’s 20-year obsession now makes complete sense: he was not after Chae-ni. He was trying to reverse what Jeon-bok chose to bury. It is a retroactive emotional gut punch, and Kim Hae-sook delivers the confession scene with the kind of quiet devastation that makes it the single most memorable moment in the finale.
The clock strikes midnight — and nobody disappears. As the feared Y2K apocalypse fails to materialize and Haeseong City exhales, the show delivers its final, most earned gesture: Chae-ni’s health crisis, the terminal illness that launched this entire story, finds a meaningful resolution tied directly to the release of the Child of Eternity’s power. The show does not pretend this is a clean miracle — it is given the weight of what it costs and what it means. The final sequence, the four of them watching the fireworks over a city they saved without anyone knowing, is exactly the right ending for exactly this kind of story. The WONDERfools began as a disaster and ended as something rarer: a series that remembered why it started.
✍️ KDramaWorlds Editor’s Take
Our honest read on why this drama is worth your time — and who it’s for.
The WONDERfools does not arrive quietly. From its very first scene — a terminally ill woman concocting a kidnapping scheme to fund her final days — it announces itself as a show that refuses to be sensible about anything. What follows is eight episodes of spectacular, lovable nonsense undercut by a genuine emotional core that earns more than it has any right to. Park Eun-bin has been excellent in serious dramas before (Extraordinary Attorney Woo), but watching her play a character this unhinged — this alive — is a different kind of pleasure. She commits completely to every physical gag, every emotional reversal, and the result is a performance that holds the entire show together even when the plot tests logic’s patience. Director Yoo In-sik, who knows his way around big-swing genre hybrids, keeps the tone calibrated: funny when it needs to be, quietly devastating when the terminal illness plot resurfaces.
The show is not without its rough edges. Cha Eun-woo’s Un-jeong is more effective as a plot mechanism than as a fully felt character — he is dependable in the lighter scenes but visibly strains in the heavier ones, where the writing asks for emotional range his performance cannot always supply. The villain’s motivations also take too long to crystallize; Dr. Ha Won-do is menacing in presence but thin in motivation until episode six, which creates a drag in the middle stretch. These are real problems. They are also the kind of problems that a show this committed to its own chaotic sincerity makes you willing to overlook, because the upside — the ensemble comedy, the found family payoff, the 1999 period detail — is too charming to dismiss. Think of it as K-drama’s answer to a Saturday morning superhero cartoon that somehow made you cry at the end. Fans of The Uncanny Counter will recognize the DNA immediately.
The WONDERfools will not satisfy viewers looking for a tightly plotted, mythology-driven superhero series. What it delivers instead is harder to manufacture: warmth. By episode eight, you will have laughed at these people, worried about these people, and — if the show has done its job — felt something when the fireworks go up over a city that has no idea it was just saved by its least likely residents. For a show this loud and this messy, that is a quiet kind of triumph. Watch it for Park Eun-bin; stay for the moment it stops being funny and becomes something you did not expect to feel this much.
