When Ok Chan-mi’s twin brother Park Won-seok dies after falling from a school window, the police rule it as suicide — but Chan-mi refuses to accept that. She transfers to his school, Yongtan High in Seoul, determined to uncover the truth behind his death. There she meets Ji Soo-heon, a brooding student who moonlights as a vigilante-for-hire, secretly punishing bullies on behalf of their victims.

🏁 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 Revenge of Others. Stop here if you haven’t finished the series.
The real killer was never who the show pretended it was. Through most of the series, Gi Oh-sung functions as the obvious villain — controlling, manipulative, shielded by his father’s political power. And he is a villain. But the actual person who pushed Won-seok off the roof is Seok Jae-beom — or more precisely, the alternate identity “Jae-jin” that Jae-beom developed after his twin brother’s traumatic death years earlier. The finale opens with Jae-beom confronting Oh-sung directly, telling him he remembers everything: that it was Oh-sung who pushed Jae-beom off a roof first, years ago, and that Oh-sung has spent the intervening time systematically gaslighting Jae-beom to keep that alter personality under his control — weaponizing it to do his dirty work.
Won-seok’s death is explained — and it complicates everyone’s grief. A key witness, Kwon Se-jin, returns from the U.S. and confirms what the show had been hinting at: Oh-sung had been blackmailing Won-seok using a photo of him with a male partner, forcing Won-seok to bully other students in exchange for silence. Won-seok wasn’t complicit by choice — he was being coerced, using homophobia as leverage. The show doesn’t flinch from this. Chan-mi has to hold two things at once: that her brother was a victim, and that he chose to hurt others rather than risk exposure.
The yacht scene is Seo Ji-hoon’s defining moment in the series. Chan-mi tracks Jae-beom down on a yacht where he’s switching between identities mid-conversation — sometimes Jae-beom, sometimes Jae-jin. She pleads with Jae-jin to release Jae-beom, recognizing that the alter is not a monster but a traumatized child who believed he was avenging his own death. In an agonizing sequence, Jae-beom — overcome with guilt over Won-seok’s death — attempts to shoot himself with Chan-mi’s gun. The gun fires its only bullet harmlessly. He is taken into police custody.
Oh-sung’s death is the show’s most deliberately complicated beat. He lures Soo-heon to a rooftop using Ji-hyun as a hostage. They fight. Oh-sung falls from the roof and dies on impact. The show refuses to make this cathartic — it doesn’t frame Oh-sung’s death as justice, exactly, though it is consequence. What follows is more interesting: the entire student body, having been informed of the full truth via circulating messages, collectively lies to the police. Every single student corroborates a false account that Oh-sung’s fall was accidental. Detective So-jung — who knows — lets it go. The school chooses Soo-heon. That collective lie is the drama’s actual emotional climax.
The epilogue earns its warmth because the show did the work to get there. Chan-mi is accepted into the Marine Corps — the goal she’d set before Won-seok died, deferred by grief and then by this investigation. Soo-heon drops out of school, his brain tumor status left deliberately ambiguous, and chooses simply to live on his own terms. The two of them leave together as a couple — finally, quietly — while their classmates cheer from behind. It’s a rare K-drama ending that feels like a real exhale: not a bow, not a fantasy flash-forward, just two people walking out into the rest of their lives. They earned it the hard way, and the show made sure you felt every step of the cost.
✍️ KDramaWorlds Editor’s Take
Our honest read on why this drama is worth your time — and who it’s for.
Revenge of Others works as well as it does because Shin Ye-eun refuses to play Chan-mi as a victim. She arrives at Yongtan High not crying, not collapsing — she arrives with a plan, a cover story, and a willingness to get physical when necessary. That’s genuinely rare in the school thriller genre, which tends to sideline its female characters once the fighting starts. Chan-mi is in the middle of every confrontation, and Shin Ye-eun carries the weight of a character who has to hold grief, rage, and tactical intelligence all at once. For a Disney+ Original that could have coasted on its platform backing, the show commits hard to earning every dark beat. Compared to the measured restraint of Juvenile Justice or the long-game architecture of The Glory, this one plays faster and more visceral — 12 episodes that rarely breathe.
The DID twist in Episode 11 is the show’s most divisive choice — and it’s worth sitting with. On one hand, using dissociative identity disorder as a plot device for a secret killer is a trope the genre has leaned on too often, and some viewers will clock the reveal as lazy. On the other hand, the show actually does the emotional work: it doesn’t treat Jae-beom as a monster, it traces his condition to a specific trauma, and it makes you watch Oh-sung weaponize that condition in real time across multiple episodes. Seo Ji-hoon plays both states — the warm, cheerful Jae-beom and the cold, haunted Jae-jin — with a precision that makes the twist feel inevitable in retrospect rather than convenient. The problem isn’t the concept; it’s that the show probably needed one more episode to fully land the weight of it.
The finale’s collective lie — every student at Yongtan High covering for Soo-heon — is the moment the drama earns its title. Revenge of Others isn’t just about Chan-mi’s revenge for her brother. It’s about what happens when enough people who’ve been quietly wronged finally see someone fight back and decide to stand behind them. The school system failed all of them. The police failed all of them. The one person who went outside the system to make bullies pay for it gets protected by a unanimous, spontaneous vote of solidarity from his classmates. It’s sentimental and slightly implausible and genuinely moving. That it works is a credit to how carefully the show built every one of those supporting characters, even the ones you barely noticed.
