Serial KillerPolice ProceduralDark PastEmergency Call CenterSuspense
Kang Kwon-joo is back leading the Golden Time Team, and Voice Season 2 wastes no time complicating her working life further — her new partner, Detective Do Kang-woo, is exactly the kind of colleague her ability makes hard to trust blindly. He reads crime scenes with an instinct that goes beyond training, recognizing a killer’s methods the way someone recognizes a language they grew up speaking. That’s not a compliment the show lets sit comfortably; it’s a question mark that hangs over every case they solve together.
The season’s actual killer, Bang Je-soo, targets police officers specifically and leaves behind trophies gruesome enough to suggest a personal grudge rather than a random pattern. What starts as a straightforward manhunt keeps bending back toward Kang-woo himself, forcing Kwon-joo to work a case where the person beside her might be as much a mystery as the one they’re chasing. Twelve episodes isn’t much runway for a story this loaded, and Voice Season 2 spends every one of them earning the reveal it’s building toward.

📺 Episode Guide
Spoiler-light recaps — enough to remember where you left off, nothing that ruins the ride.
EP 01
Episode 1
Aug 11, 2018
A car crash that looks like a murder-suicide is exactly the kind of case Na Hong-soo wants closed fast, and exactly the kind Kang Kwon-joo can’t leave alone — her ear catches a detail in the call that doesn’t fit the official story. She starts working a theory that the crash was remote-triggered, not accidental, and that theory is what puts her in the same room as Do Kang-woo, a detective whose read on the killer’s method comes from somewhere far more personal than police training.
EP 02
Episode 2
Aug 12, 2018
The tow-truck driver they arrest fits the crime almost too neatly, and Kang-woo isn’t buying it — to him, a confession this clean smells like someone else’s cleanup. Kwon-joo’s read of the evidence backs up her manipulated-murder theory, but it’s Kang-woo’s instinct that reframes the whole case: this isn’t the killer, this is a tool the real one used and was always willing to discard.
EP 03
Episode 3
Aug 18, 2018
Hwang Ki-hyuk swears he’s innocent with the kind of conviction that usually means someone’s telling the truth, which only complicates a case Kang-woo already can’t approach with any distance. A trapped-woman call turns into a clock-against-the-wall rescue, and it’s in the chaos of it that Kang-woo’s methods start looking less like technique and more like something he’s actively fighting to control — a detail Kwon-joo clocks, even if she doesn’t say it out loud yet.
EP 04
Shh!
Aug 19, 2018
A suspect drops dead in custody of what looks like natural causes, and Kang-woo’s first read is that someone silenced a loose end before it could talk. Kwon-joo’s ear catches the same signature on a supposed suicide call — staged just well enough to fool anyone not listening as closely as she is. The killer isn’t improvising anymore. He’s cleaning house.
EP 05
Shh!
Aug 25, 2018
Rescuing a fellow detective’s kidnapped wife should be the one case where everyone’s on the same side, but Kang-woo’s team and Na Hong-soo’s unit spend as much energy fighting each other as the kidnapper. Then Kang-woo hesitates — just long enough — before pulling a drowning suspect out of the water, and that hesitation is what the episode has been building toward. It isn’t procedure. It’s rage he’s stopped bothering to hide, and Na Hong-soo notices exactly what it looks like.
EP 06
The Accomplices With The Star Coins
Aug 26, 2018
Turning the investigation on their own chief was always going to be delicate, and one overeager move from inside the Golden Time Team is enough to tip their target off before they’re ready. Then the killer does something no one saw coming: he approaches Kwon-joo directly, compliments her work like a peer rather than a target, and hands her photographs that put Kang-woo at the scene of a murder she never knew about. It’s not a threat. It’s an introduction, and it works exactly the way he wants it to.
EP 07
Episode 7
Sep 1, 2018
A drug case that starts as a straightforward supply-chain investigation keeps leading back to names the Golden Time Team recognizes, and that’s the real discovery here — their killer isn’t operating in isolation, he’s plugged into an underworld deep enough that half the team’s usual sources turn out to be compromised. Every lead they trust a little too quickly this episode comes back to bite them.
EP 08
I Got Flowers Today
Sep 2, 2018
Bang Je-soo finally gets a name and a face on-page this episode, caught mid-cleanup after killing Ms. Hwang, and his standoff with Na Hong-soo at the scene is the first time the show lets its villain and its most compromised cop share a frame. Na Hong-soo uses the moment well, feeding Kwon-joo just enough about Kang-woo’s blackout episodes and his dead partner to make her doubt the one person she’s been trusting completely.
EP 09
I Got Flowers Today
Sep 8, 2018
Just as the team closes in on the wrong suspects in a stabbing case, the episode drops its biggest bomb yet through the most clinical delivery possible: a doctor casually confirming that Kang-woo’s father, Kosuke, was a taxi driver with dissociative identity disorder who collected human ears as trophies. The show doesn’t dramatize the reveal, which makes it land harder. Kang-woo’s past and the killer’s present method are no longer running parallel — they’ve become the same shape.
EP 10
Episode 10
Sep 9, 2018
Confirmation is worse than suspicion — Kang-woo is, in fact, the son of the murderer Matsudaga, and the episode spends less time on the reveal itself than on watching him absorb it. The Golden Time Team’s trust doesn’t collapse all at once, but it visibly strains, and the killer reads the crack perfectly, pushing exactly where it hurts. This episode is less about a suspect than about whether inheritance is destiny, and Kang-woo doesn’t get an answer — just a question he now has to live inside.
EP 11
Era Of Hate
Sep 15, 2018
Clearing Kang-woo’s name should feel like relief, and for about one scene it does — long enough for him to finally tell Kwon-joo the whole truth about his past instead of letting her piece it together secondhand. Then Agent Jin’s dark-web dig into Bang Je-soo’s “Doctor Fabre” operation turns up a target list with the team’s names on it, and Bang Je-soo answers by going after Jin Seo-yool directly and putting an ultimatum on Kwon-joo’s desk. Whatever peace this episode offers is borrowed time.
EP 12
Era Of Hate: For The Golden Time Team!
Sep 16, 2018
That image — Bang Je-soo surrendering with an icebox that’s actively dripping blood — should read as the end of the chase. Kang-woo knows immediately it’s the opposite. The finale collides Dr. Fabre’s network with the Golden Time Team head-on, and it costs what a season like this was always going to cost: Kwon-joo critically injured in a bomb blast, one of Kang-woo’s own revealed as quietly loyal to Bang Je-soo all along, and Kang-woo left holding a hatred that was never really about him and doesn’t fully go away.
🏁 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 Voice (Season 2). Stop here if you haven’t finished the series.
What actually happened Bang Je-soo walks into a police station and turns himself in carrying an icebox that’s visibly dripping blood — a surrender Kang-woo immediately reads as the start of something worse, not the end of the chase. He’s right. What follows is a full-scale collision between Dr. Fabre’s criminal network and the Golden Time Team, ending in a bomb explosion that leaves Kwon-joo critically injured and her fate genuinely uncertain as the season closes.
Kang-woo’s inheritance The season’s other unresolved thread is personal rather than criminal: Kang-woo spends the finale confronting Bang Je-soo not just as a cop chasing a killer, but as the son of a murderer wondering how much of his father’s violence lives in him. The show never gives him a clean answer, which is the point — some of what he’s carrying doesn’t get put down just because the case closes.
The traitor inside Just as damaging as the bomb is the quieter reveal that one of Kang-woo’s own has been loyal to Bang Je-soo the entire time, apologizing for the betrayal only after it’s already done its damage. It confirms what the season has been implying since episode six — Bang Je-soo’s manipulation reached inside the Golden Time Team long before anyone there realized it.
What’s left unresolved Kwon-joo’s condition, the full extent of Bang Je-soo’s network, and whether Kang-woo can separate himself from his father’s legacy are all left open rather than answered. That’s an unusual choice for a season finale, and it plays less like an oversight than a deliberate refusal to hand the audience comfort it hasn’t earned.
The KDW verdict Voice Season 2 ends the way its whole runtime has been building toward: expensively, and without a victory lap. The season was never really about whether the Golden Time Team would catch Bang Je-soo — it was about what the hunt cost each of them, and that bill comes due in full in the finale’s last ten minutes.
✍️ KDramaWorlds Editor’s Take
Our honest read on why this drama is worth your time — and who it’s for.
🔪 Serial Killer Hunt
🧠 Psychological Warfare
📞 Golden Time Race
💔 Inherited Violence
Lee Ha-na is the connective tissue holding this franchise together, and Voice Season 2 uses that continuity well — Kang Kwon-joo returns leading the Golden Time Team, but this time her partner is Do Kang-woo, played by Lee Jin-uk with a controlled intensity that feels deliberately different from Jang Hyuk’s grief-driven detective in Season 1. Where Season 1 ran on loss, Season 2 runs on suspicion — Kang-woo’s own unclear past makes him the season’s second mystery, running parallel to the actual serial killer investigation.
What sets this season apart from a standard cop-versus-killer format is how personal the show insists on making it — Kang-woo isn’t just hunting Bang Je-soo, he’s confronting a version of his own bloodline in the process. That’s a heavier ask than most procedurals attempt, and it’s a similar structural gamble to the one Nine Puzzles makes years later: the profiler and the case become impossible to fully separate.
The season’s willingness to end badly — genuinely badly, not just dramatically — is what keeps it from feeling like formula. Kwon-joo doesn’t walk away clean, the traitor reveal doesn’t get punished on screen, and Kang-woo’s inheritance question is left open rather than resolved with a speech. For a show built around a golden-time countdown, it’s oddly comfortable letting some clocks just run out.

⚖️ Final Verdict
What works
•Lee Jin-uk grounding a role that easily could have tipped into melodrama
•A season-long mystery that pays off its own setup instead of stalling
•Bang Je-soo as a genuinely unsettling, personally-invested antagonist
What to know first
•Middle episodes (7-9) prioritize plot mechanics over character beats
•The finale’s cliffhanger won’t satisfy viewers who want closure
•Familiarity with Season 1 helps contextualize Kwon-joo but isn’t strictly required
8.5 / 10— A tighter, more personal season than its premise promises, undercut only by an ending that refuses to let anyone off easy.
