The Husband Episode 4 kicks things into an even higher gear, and honestly, I had to pause a few times just to process how much ground this show covers in one hour. Between Tae-ju making an ally out of nowhere, a shocking murder in captivity, and a full-blown heist at a national forensic lab, this episode earns its place as one of the most eventful yet.
Se-yun’s Doubts Come Back to Haunt Us
The episode opens on a flashback, and it’s a gut punch right from the start. We see Se-yun waiting up for Tae-ju, clearly unsettled by how much he’s changed. She calls him out gently, noting that he’s been missing family time and acting differently. He brushes it off, blaming a work emergency at the hospital, but you can tell she’s not buying it. She wonders out loud if he’s hiding something from her. Knowing what we know now about Tae-ju’s double life, this flashback hits so much harder the second time around.
The Chase Through the Alleys
From there, we’re thrown right back into the chaos of Tae-ju’s hospital theft and the car pursuit that follows once police catch on. In the scramble, Tae-ju manages to duck into an alley and disappear from the vehicle chase, but that’s far from the end of it. Officers pursue him on foot, and the situation turns violent fast. One officer ends up seriously hurt after a physical struggle with Tae-ju. What struck me here is that Tae-ju doesn’t just leave him there. He administers first aid, calls in an ambulance for the injured officer, and only then takes the man’s gun before slipping away again. It’s a small moment, but it tells you a lot about who Tae-ju still is underneath all this desperation.
Se-yun’s Escape Attempt Ends in Heartbreak
While Tae-ju is out running from the law, things take a darker turn back at the captivity site. The kidnapper actually stops by the police station to scope things out, which is a bold move on his part. While he’s there, he checks the camera feeds and catches Se-yun in the middle of an escape attempt. She’s already broken free of her room and is trying to help Seon-ja when she spots him. She freezes. He doesn’t hesitate. A brutal headbutt knocks her unconscious, and just like that, her one shot at freedom is gone.
Enter Su-hyeong: A Man With His Own Vendetta
Meanwhile, Tae-ju takes a train out to meet the mysterious man who’s been guiding him. When he arrives, the man leads him into a building lined with case files and evidence boards. Tae-ju’s mind immediately jumps to the worst conclusion: that this stranger is somehow connected to the kidnapper. He pulls the stolen police gun on him without hesitation.
Turns out, he’s got it completely wrong. The man introduces himself as Su-hyeong, a former police officer whose own wife was taken and killed by the same kidnapper six years ago. He’s not the enemy. He’s hoping to use Tae-ju as leverage to finally track down the man who ruined his life. Things get tense fast, though, because as Su-hyeong explains his story, Tae-ju gets distracted, and Su-hyeong takes the opening to attack him.
Tae-ju, thinking on his feet, uses the stolen hospital medicine to subdue Su-hyeong instead. Once things calm down, Su-hyeong lays out exactly what happened to him: the kidnapper conned him out of 100 million won in ransom money and never returned his wife alive. Now he’s obsessed with hunting the man down and killing him himself. He’s got a police contact who gave him access to the original ransom call audio, and after comparing notes, he’s convinced he and Tae-ju are chasing the exact same person. He’s even managed to connect this case to another kidnapping and murder from the past.
A Death in the Dark Room
Back in captivity, Se-yun wakes up in the same dark room, her hands bound behind her back. The CCTV camera flickers on, and she hears something dragging closer. It’s the kidnapper, and he’s pulling a sledgehammer behind him. What happens next is brutal: he kills Seon-ja right in front of her. Se-yun completely breaks down, screaming at him to kill her too. This scene is rough to watch, and it firmly establishes just how far this kidnapper is willing to go.
Tae-ju Turns the Tables on His In-Laws
On the investigation side, police are using street CCTV to close in on Tae-ju’s location and have gone public, asking for the community’s help finding him. What they don’t know is that Tae-ju now has backup in Su-hyeong, who convinces him to go collect the ransom money directly from his in-laws.
This confrontation is genuinely tense. Tae-ju pulls the gun on Dong-chan and Soo-kyung to get what he needs, and understandably, they’re devastated, assuming this confirms he only married their daughter for her money. They plead with him to let her go. Tae-ju tries to explain that he genuinely believes Se-yun is still alive and that he needs this money to save her. When Dong-chan threatens to call the police, Tae-ju fires two warning shots into the air and escapes with the cash just as officers arrive on scene.
Do-sik later learns that Tae-ju insists Se-yun is alive, and that detail leaves him rattled. Something about the way Tae-ju said it doesn’t sit right with him.
The Manhunt Goes Public
By the next morning, news breaks that Tae-ju robbed his own in-laws of the ransom money. The kidnapper watches the coverage with an unsettling kind of amusement, clearly curious about what Tae-ju is planning next. At the hospital, some of Tae-ju’s colleagues aren’t surprised at all, muttering that they always suspected something was off about him. Chi-ung, surprisingly, is the one who steps up to defend him.
Breaking Into the NFS
With Su-hyeong’s help, Tae-ju manages to infiltrate the National Forensic Service using a fake badge to request case evidence. And somehow, it works. He pulls off the entire operation without a hitch and walks out with exactly what he and Su-hyeong needed.
Face to Face Through a Screen
Back at the captivity site, the kidnapper leaves food out for Se-yun. While reaching for it, she spots a piece of metal poking out from under the door frame. She inches toward it carefully, aware she’s being watched the whole time. Then, out of nowhere, the kidnapper’s camera feed cuts out. A new feed opens in its place, and there’s Tae-ju, staring back through the screen.
Why Su-hyeong Changes Everything
The moment Su-hyeong showed up, I knew this show had just leveled up. Played by Park Byung-eun, he brings a weight to this story that Tae-ju alone couldn’t carry. His background in police work means he actually understands protocol and investigative tactics, and that expertise might be exactly what Tae-ju needs to have any real shot at finding his wife. Two people working together toward the same goal changes the entire math of this hunt.
But Su-hyeong’s backstory does something else too. It works as a warning shot for what’s coming. If a former cop with real resources and six years of obsessive searching still couldn’t save his own wife, what does that say about Tae-ju’s chances? That’s the scary part. Su-hyeong has been chasing this ghost for six years, and this is the closest he’s ever gotten. That kind of desperation can cut both ways. It might help Tae-ju. It might also blow everything up.
Then there’s the NFS break-in, which honestly made me laugh a little given the circumstances. Tae-ju is the subject of an active nationwide manhunt, and he just casually strolls into a national forensic lab and walks out again like it’s nothing. The audacity of it is kind of thrilling to watch. It raises the question of how far he’s actually willing to go before this is over, and at this point, I don’t think there’s a line he won’t cross.
Taken as a whole, this episode moves fast and doesn’t waste a single scene. Both the kidnapper and Tae-ju are quietly building toward their inevitable collision, and the tension is mounting episode by episode. If you’re not caught up on this one yet, The Husband deserves a spot on your watchlist this weekend.
