“I’ve liked you, hyung, since then.” — Yoo Seong-won, Episode 9
A dead dance student, a curse note written in blood, a campus convinced its hallways are haunted. Flex X Cop 2 spends the first half of episode 9 looking like it has finally let a ghost into its own procedural, then spends the second half quietly explaining away every piece of the haunting with pharmacology and institutional rot instead. Meanwhile, in a workshop across town, a man I-soo has trusted for years says a sentence that recasts an old friendship as something he never knew he was inside of.
Ratings cooled slightly after episode 8’s record run, settling at a 6.7 percent national average with a 7.9 percent peak, a 6.9 percent Seoul-metro average, and a 2049 demographic peak of 2.14 percent. A dip after a new high is ordinary, and nothing about the number suggests the audience minded a two-track episode this dense.
A Ghost Story That Turns Out to Be a Supply Chain
Korean screens have a long-running subgenre built around the dance studio or the practice room after hours — a resentful ghost, usually a dead student, haunting the exact space where the living compete for a role. The trope works because arts schools in Korea run on a brutal, audition-based hierarchy, and a vengeful spirit gives that competition a supernatural scapegoat instead of a human one. This episode borrows every visual signature of that genre, a blood-written curse, a figure caught on grainy security footage, a student who dies clutching a ceremonial dance sword, and then refuses to let any of it be a ghost at all.
What killed dancer Moon Se-yeon wasn’t a curse or a blade wound. It was an asthma attack triggered by a hallucinogenic drug hidden inside a charm sold at a novelty occult shop, a trinket marketed as superstition that turned out to be a genuine narcotic in circulation among students desperate enough to believe in curses in the first place. The show doesn’t just stage a twist here. It argues that the ghost story itself was always a cover for something a lot more mundane and a lot harder to prosecute.
A Casting Scandal Dressed as Superstition
Part of what makes the setup legible to viewers unfamiliar with Korean arts education is understanding how much is riding on a single lead role at a school like this one. Specialized arts high schools admit students by audition, track their standing by performance casting, and treat a lead part in the annual showcase as a credential that can shape a dancer’s entire career trajectory. Real casting-corruption scandals, parents paying for a child’s placement, have surfaced in Korean entertainment news often enough that the premise here lands as recognizable rather than far-fetched.
Principal Jeong Ju-hee, a former dancer sidelined by a herniated disc before taking over the school, carries exactly that kind of rumor: that she hands the lead role to whichever family pays for it. The investigation never produces hard evidence against her, and the episode is careful not to convict her in the dialogue either. What it does instead is let the suspicion sit there, unresolved, a believable motive nobody quite proves.
A Dead Student’s Story That Doesn’t Quite Add Up
The case keeps circling back to Baek Yu-na, a student who died in the same studio seven months earlier, wrist slit, a curse written in her own blood, ruled a suicide after a text apologizing to her mother surfaced. One account of the episode treats her death as a loose end worth sitting with precisely because it resists a clean read: rumor held that Yu-na’s mother had bribed Jeong Ju-hee to secure her the lead role, which makes her suicide afterward a strange thing to do if winning the role was ever really the point. If money changed hands and got her what she wanted, why would getting it be the thing that ended her?
The episode doesn’t resolve that tension, and it shouldn’t. A guard’s lie about disabled security cameras establishes that someone wanted Yu-na’s death to go unwitnessed, which keeps the suicide ruling honest without fully closing the case around it. Whatever happened to Baek Yu-na remains the one thread this episode raises and declines to finish pulling.
Flex X Cop 2 Episode 9 Ending Explained
With the curse pouches traced to the same drug supply, the show gives Song Ga-eun, the student who sent Yu-na’s original curse note and inherits the lead role after Se-yeon’s death, her own pouch and her own hallucinatory breakdown mid-rehearsal. She swings a real sword at classmates she sees as monsters, and I-soo catches the blade with his bare hand, opening a wound deep enough to end the episode on his own blood rather than a suspect’s. It’s a small but pointed reversal for a character who has solved every case so far by spending money rather than risking his body — for once, the show’s most reliable tool doesn’t work, and he has to physically absorb the danger himself.
The harder question the episode leaves open belongs to I-soo’s own life outside the case. A shaman warns him that something is still lingering and tells him never to open his door to anyone, and the next morning his house turns up ransacked while he was asleep on prescription medication, with no memory of what happened and a doctor confirming the drug carries no side effects that would explain it. The show doesn’t say who did it. It only lets that uncertainty sit next to Yoo Seong-won’s confession that his attachment to I-soo predates what I-soo remembers of their friendship, close enough in timing that the two mysteries start to feel like they might be the same one.
What Episode 10 Might Bring
If the season’s pattern holds, the curse case closes here and the Seong-won thread keeps expanding into the space it just opened. The glimpse of him bringing a new woman into his studio suggests his pursuit of a fresh subject continues regardless of how much suspicion has started circling him, and I-soo’s reed sample now sitting with Hye-ra points toward some kind of forensic confirmation becoming the next concrete step toward building a case against him.
Verdict
This is an episode built on a genuine bait-and-switch that mostly earns its reveal rather than feeling like a cheat: the ghost-story trappings are thick enough in the first half that the eventual drug explanation lands as a real rug-pull rather than an obvious setup. Ahn Bo-hyun sells the blade-catch with more physical strain than the show usually asks of him, and Yoo Seung-ho continues to make Seong-won’s calm the scariest thing about him, delivering his confession about I-soo in the same even tone he’d use to describe a sculpture.
The ratings dip after episode 8’s high is unremarkable set against how much plot this hour is carrying, two cases advancing at once without either one feeling shortchanged. With a student’s death only partly explained, a protagonist whose house was invaded for reasons nobody can name, and a confession that reframes a decade of friendship, Flex X Cop 2 is entering its back stretch with more loose threads live at once than at any earlier point in the season.

Our Verdict: 🗡️🪄 — A curse that turned out to be chemistry, and a confession that didn’t need one.
