EP 01

He Saw My Face

September 23, 2016 · tvN

Kim Je Ha — a highly trained ex-Special Forces soldier on the run — witnesses something he shouldn’t while hanging a banner outside a presidential candidate’s office. After single-handedly dismantling an armed assault with terrifying precision, he catches the attention of JSS Security and, more importantly, the candidate’s powerful wife Choi Yoo Jin. Meanwhile, in Spain, a girl named Go An Na calls out for parents who never come.

EP 02

The K2

September 24, 2016 · tvN

Je Ha evades every JSS team sent after him — a fact that impresses and unsettles Chief Joo, who knows exactly what this man is capable of. Yoo Jin orders An Na brought back to Korea from Spain, and the pieces of a complicated political and personal chessboard begin falling into place. Je Ha’s status shifts from target to asset.

EP 03

The Setup

September 30, 2016 · tvN

An assassination attempt on Yoo Jin serves a dual purpose — Se Joon uses the chaos to boost his campaign while Yoo Jin walks away with more leverage than before. Chief Joo extends Je Ha a formal offer to join JSS, and despite every instinct against it, Je Ha accepts. The rivalry between Se Joon and Park Kwan-soo sharpens as our reluctant bodyguard steps into the political arena.

EP 04

Mutual Leverage

October 1, 2016 · tvN

Yoo Jin makes her pitch plain: she doesn’t need a soldier, she needs a weapon — and Je Ha needs access she can provide. The two form a calculated alliance built on shared hatred of Park Kwan-soo. Neither trusts the other. Both need what the other has. Je Ha begins guarding An Na and realizes quickly that this assignment is nothing like what he expected.

EP 05

He Was a Wolf

October 7, 2016 · tvN

At a funeral, Yoo Jin walks into a trap she cannot escape — and the only person between her and disaster is Je Ha. He gets her out. Their partnership, grudging and transactional until now, shifts into something more visceral. An Na watches Je Ha from a distance and begins to see, for the first time, someone she might actually trust.

EP 06

The Secret Offer

October 8, 2016 · tvN

Yoo Jin dangles information about Je Ha’s past as bait — and for a moment, it works. Meanwhile An Na makes a move no one saw coming: she escapes Cloud Nine in search of her father. The chase reveals how closely her fate is tangled with everyone else’s secrets, and Je Ha finds himself caught between his mission and a growing protectiveness he didn’t plan for.

EP 07

A Dangerous Promise

October 14, 2016 · tvN

Je Ha reaches An Na before anyone else does and makes her a promise he means to keep. Yoo Jin, reading the situation with her usual cold precision, gives away information that should cost her — but trades it strategically for a new alliance. The gap between An Na and Je Ha closes, and the emotional stakes of the series begin to outpace the political ones.

EP 08

Going Viral

October 15, 2016 · tvN

An Na’s disappearance leaks online and goes viral before JSS can contain it. Se Joon commissions an investigation into Yoo Jin’s family company — a move that puts everyone on edge. Je Ha scrambles to manage the crisis while keeping An Na shielded from the chaos, and a deeper investigation into Se Joon’s own past begins to surface uncomfortable truths.

EP 09

Family Ties

October 21, 2016 · tvN

An Na meets her uncle Choi Sung-won for the first time — a man who claims to want to help her and who reveals details about her mother, Ume Hye-rin, that reframe everything An Na thought she knew. Je Ha receives another employment offer that complicates his position at JSS. Everyone in this story has a second agenda, and An Na is beginning to understand just how many of them involve her.

EP 10

The Tribute

October 22, 2016 · tvN

An Na organizes a public fashion event in tribute to her late mother Hye-rin, using the platform to press for answers about how she died. The gesture draws public attention — and political heat. The investigation into Se Joon takes a sharp turn as new evidence surfaces, and the web of corruption connecting Se Joon, Kwan-soo, and the Choi family pulls tighter.

EP 11

Controlled Chaos

October 28, 2016 · tvN

An assassination goes wrong — but Yoo Jin, as always, turns a crisis into an opportunity. She and Se Joon come out stronger than before. Je Ha brokers a quiet deal with Park Kwan-soo, trading information for access, while the revenge plan that brought him to Korea in the first place moves closer to its final shape. The alliance between Je Ha and Yoo Jin is fraying at the edges.

EP 12

Anna’s Apology

October 29, 2016 · tvN

An Na turns to Chairman Choi for help getting justice for her mother. A viral post triggers a formal reinvestigation into Hye-rin’s death — and a witness comes forward claiming they saw Yoo Jin inject something into Hye-rin’s neck that night. Yoo Jin, cornered, admits she let Se Joon believe she was responsible — but denies being the killer. In an unexpected move, she gives Je Ha full access to Mirror, JSS’s surveillance system. Something is shifting.

EP 13

Striking Back

November 4, 2016 · tvN

Se Joon attempts damage control after Yoo Jin’s public statement — but his credibility as a presidential candidate is now in freefall. Yoo Jin tries to get An Na out of the country. Je Ha, chasing the president’s son with explosive Kumargate evidence, puts himself in serious danger. And somewhere in the middle of all of it, An Na and Je Ha acknowledge what they feel for each other — and decide to fight back.

EP 14

The Fall

November 5, 2016 · tvN

Je Ha is critically wounded trying to retrieve Kim Suk-han’s memory card — and falls into a coma. Park Kwan-soo, never one to miss an opening in the chaos, moves to bring down JSS entirely. Sung-won searches desperately for the memory card Je Ha managed to take. An Na boards a plane to Spain, unaware of how badly Je Ha has been hurt.

EP 15

Cloud Nine

November 11, 2016 · tvN

Sung-won invades Cloud Nine with a bomb while An Na is mid-flight to Spain. Yoo Jin refuses to surrender the compound without a fight. Je Ha agrees to hand over the memory card to Park Kwan-soo in exchange for leverage — but the bomb in Cloud Nine’s sub-level cannot be defused, and the situation spirals toward a collision that no one can walk away from cleanly.

EP 16

I’m Your Mother’s Murderer

November 12, 2016 · tvN

The finale. Chairman Choi takes An Na hostage and ends up trapped in Cloud Nine alongside Se Joon and Yoo Jin — and a bomb that cannot be turned off, because Kwan-soo tricked Sung-won. Yoo Jin tells An Na the truth she has been waiting years to hear. Se Joon makes his final choice. Je Ha survives. An Na inherits everything and builds a life with the man who kept his promise.

Full spoilers ahead — everything that happens in the finale and what it all means.

The trap closes on Cloud Nine. The finale begins with Chairman Choi Sung-won taking An Na hostage and forcing his way into Cloud Nine — only to find himself locked in the facility with Jang Se Joon, Choi Yoo Jin, and a bomb that Kwan-soo rigged specifically so it cannot be diffused. Kwan-soo tricked Sung-won into triggering a mechanism with no off switch, ensuring that everyone inside pays for what they know. The political endgame has become something far more primal: survival in a sealed room.

Yoo Jin finally tells the truth. With nothing left to protect and no political future to preserve, Choi Yoo Jin does the one thing she has refused to do for years: she tells An Na the full story of the night Ume Hye-rin died. Yoo Jin did not kill her. She admits she allowed Se Joon to believe she was responsible — it gave her control over him — but the actual murderer is Choi Sung-won, who injected the lethal substance into Hye-rin’s neck while Yoo Jin stood by and said nothing. It is a confession that absolves Yoo Jin of one crime while implicating her in another, and it is delivered with the same cold precision she brings to everything.

Se Joon’s final act. Whatever else Jang Se Joon is — a coward, a liar, a man who used his own daughter as a political liability to be hidden away — he chooses, at the end, to step toward the bomb rather than away from it. He pulls it into a reinforced glass room with him and reaches for Yoo Jin. They embrace as the explosion triggers. It is the show’s most dramatically charged image: the opportunist and the manipulator, finally together, finally honest, in the only moment that cost them nothing left to lose.

Justice, earned slowly. Je Ha survives. He testifies at South Korea’s Iraq headquarters about the Blackstone incident — the operation that framed him and killed the woman he loved — and the record is corrected. An Na releases the contents of the memory card publicly, exposing the Kumargate corruption that Kwan-soo and Sung-won spent the entire series trying to suppress. Both men pay for what they did. The political machine that crushed everyone it touched is finally dismantled, not in a single heroic moment, but through the accumulation of truth that could no longer be contained.

An Na inherits, Je Ha stays. An Na becomes the heir to the wealth left behind by her father and stepmother — a fortune built on schemes and secrets she had no part in creating. She uses it differently. Je Ha keeps the promise he made her in Episode 7, the one that mattered more than anything else in the story. The ending is quieter than the chaos that preceded it — two people choosing each other after surviving a world that tried its best to destroy them both. The K2 is a drama about what happens when a weapon decides it’s done being used — and the cost of that decision for everyone in its path.
