In the Nine Puzzles episode 6, it takes a darker turn. The puzzle is getting harder, and I-na is chasing every clue. This time, she takes her findings straight to Han-sam. She’s focused, calm, and one step ahead. She collects all the call logs and connections. One call log catches her eye. Chi-muk called Yoon-su three times before he died. But Yoon-su’s alibi is strong. Almost too strong.
Yoon-su is the head of a big construction company. I-na decides to meet him in person. She wants answers. But Yoon-su isn’t helpful. He gets angry when questioned. He asks her to leave. I-na doesn’t stop there. She shows Chi-muk’s photo to the front desk. The receptionist looks nervous. That’s all I-na need to know. She leaves, quiet but sure. She has a lead.
Back on the other side, Han-sam is meeting Yang-hee. He asks if she knows Yoon-su. She says yes. Yoon-su once refused to officiate her wedding. He just didn’t want to be involved. Yang-hee also mentions that Chi-muk and Yoon-su had a strange relationship. It started friendly, but later, Yoon-su turned cold. He treated Chi-muk poorly.
Then things shift quickly. Han-sam gets a call. Yoon-su is found dead. Right inside his own office. I-na rushes to the scene. The killer stabbed him below the sixth vertebra. The wound seems intentional. Like the killer wanted the body found quickly. Not hidden.
While searching the office, I-na finds another puzzle piece outside the autopsy hospital. It’s the fourth one. This time, it’s a clown. The clue points to Yoon-su. Around the clown are dolls, cotton candy, dancing children, a sandcastle, and a Ferris wheel. It’s a clear image. It looks like an amusement park.
Clown Puzzle Points to Amusement Park Mystery
Han-sam is worried. He thinks the killer knows too much about I-na. She doesn’t panic. She believes the killer doesn’t want her dead. If he did, she says, she’d be gone already. He wants her to solve it. That’s the whole point.
She studies the drawing again. The background looks like an amusement park. She starts searching for similar parks in Korea. One park matches the drawing. She visits. The park is closing soon. She talks to one of the workers. He says no accident or death ever happened there.
In another thread, we hear more about Chi-muk and Yoon-su. Chi-muk used to get drunk and argue with Yoon-su. He asked him for more resort space. But Yoon-su didn’t care. He tolerated Chi-muk. He looked down on him, but never said much in return.
Meanwhile, Han-sam follows another clue. Choi San, a team member, points out something odd. A handkerchief that was shown in early crime scene photos is now missing. It’s not in the evidence box. That’s a problem. It could be a mistake—or the killer removed it on purpose.
Apartment Connections
I-na heads to Mi-young’s apartment. She checks property records. She finds a big link. Chi-muk used to live there before Mi-young. And before that, the first owner was Yoon-su. That connects all three of them. Chi-muk, Mi-young, and Yoon-su. One apartment, three lives. Now the question is—what happened there?
The episode doesn’t solve much, but it gives just enough to keep us hooked. I-na is making progress. Slowly. Each clue opens more questions. Yoon-su’s death changes everything. He knew something. And now he’s gone. I-na is close, but the truth keeps shifting.
The killer is clever. He leaves just enough behind. But not too much. The puzzle pieces are not random. They all mean something. Each victim is tied to a place, an image, and a past story. The amusement park drawing may be more than a background. Maybe it’s a place where it all started.
The clue about the handkerchief could change things. If it was taken after the crime scene, someone is cleaning up. Maybe not just the killer. Maybe someone helping him. Or someone else trying to hide something.
The connection between the apartment and the three people is huge. It’s not just a place they lived. Something happened there. Something bad. That apartment might be the key.
As the case builds up, I-na’s role is more important than ever. She sees what others don’t. She notices small details. Her instincts are strong. Even when others doubt her, she keeps moving.
This episode adds new layers to the story. More mystery, more clues, and one more victim. The puzzle killer is still ahead. But I-na is closing the gap. Slowly, but clearly. The mystery continues! Set your reminders! Disney+ will release Nine Puzzles episodes 7–9 on May 28th at 4 PM KST, and episodes 10 and 11 will follow on June 4th. You won’t want to miss it!
