Disney+ is bringing a new mystery series that’s already catching a lot of attention. The show is called Nine Puzzles, and it’s a dark mystery thriller with a story that mixes memory loss, crime, and deep suspicion.
At the center of the story is Ina, played by Kim Da-mi. She’s a profiler who was the only witness to a murder that happened ten years ago. But the catch? She lost all memory of it. That one event changed her life completely. Now, the same type of crime has started again, and she’s thrown back into the past she doesn’t fully remember.
Han Saem, played by Son Seok-gu, is a detective. He’s been on this case for a decade. He’s not just chasing the killer—he’s also chasing the truth about Ina. For years, he believed she might be the one responsible. But now, he has to work with her to solve the case. That uneasy tension between them adds a lot to the storyline.
The recently released character posters and videos give a first look at the main cast. Each one shows a piece of the puzzle—literally and emotionally. The posters are simple but powerful. They show the weight the characters carry and the doubts that surround them. Ina’s poster shows her troubled, deep in thought, unsure of what’s real and what’s missing from her mind. The murder of her uncle still haunts her. She isn’t just profiling the killer—she’s also questioning herself. That mix of doubt and drive makes her character feel very real.
Han Saem’s poster includes the line, “I have thought you are the most likely suspect for 10 years.” That sentence alone tells a lot about where his head is at. He’s torn between his duty as a detective and his instincts, which point straight at Ina. The two have to work together, but it’s clear that trust won’t come easily.
A Cast That Feels Real
Yang Jeong-ho, played by Kim Sung-gyun, leads the 2nd Violent Crimes Unit. His role adds another layer to the story. He believes in evidence, not just theories. In his line, “Can you be sure that you know everything about Yoon Ina?” the pressure increases—not just on Ina, but on Han Saem too.
Then there’s Choi San, the youngest team member, played by Hyun Bong-sik. His poster brings some lightness with the line, “But come on, why do you keep calling me the youngest? I’m old too…” It’s a simple line, but it makes him instantly relatable. Even in a heavy plot, he adds a bit of humor and realism that helps balance the show’s tone.

The character video adds more detail. It’s fast-paced but clear. Ina looks calm on the outside but shaken on the inside. She’s trying to follow clues, track behaviors, and find logic in chaos—all while questioning if she’s missing something big. Her calmness is almost haunting.
Han Saem, on the other hand, doesn’t hide his feelings. He’s sharp, intense, and straightforward. He challenges his superiors and trusts no one too easily. His focus is always locked on the case, but his tension with Ina makes every scene between them interesting. Nine Puzzles Disney Plus character posters show that this series won’t just be about solving a crime. It’s also about broken trust, long-held doubts, and people trying to move forward while being stuck in the past.
Yang Jeong-ho’s character brings structure to the team. He keeps things professional, focuses on the facts, and doesn’t let emotions lead the investigation. He’s not just there to lead—he’s there to keep everything grounded. And Choi San, with his casual tone and laid-back energy, gives the team a much-needed contrast. He’s younger, more in tune with modern thinking, but he also holds his ground. His chemistry with Han Saem, especially during tough investigations, adds moments of relief without being too much.

What Makes ‘Nine Puzzles’ Worth Watching?
Nine Puzzles doesn’t just rely on shock value or standard whodunit tropes—it weaponizes memory and trust as part of its mystery. What’s refreshing is how the series makes the crime investigation feel psychologically personal. Instead of focusing solely on the killer, it focuses on how trauma can blur the truth. I-na’s memory loss isn’t just a plot device—it’s a character in itself, constantly shifting the stakes.
Watching Kim Da-mi and Son Seok-gu go toe-to-toe is thrilling in the emotional sense. Every scene between Ina and Han Saem feels like a psychological chess match. You’re not just wondering who did it—you’re wondering if they’ll survive working together. The tension isn’t romantic—it’s raw, mistrustful, and oddly captivating.
K-drama fans who are accustomed to flashy visuals might miss this: the Nine Puzzles posters are strategically designed. They don’t just introduce the characters—they foreshadow their arcs. Han Saem’s line about suspecting Ina for ten years? That’s not a teaser. It’s a ticking time bomb that colors every decision he makes. If you loved the slow burn of Stranger or the emotional gray zones of Beyond Evil, this show will hit that same sweet spot. It’s not here to spoon-feed you. It’s here to make you question what you know—and what the characters don’t even know about themselves.
