Spoiler-light recaps — what happens in each episode, without ruining the big moments.

EP 01

The Fall

December 6, 2025 · tvN

Kang Da-wit is at the apex — celebrated judge, social media darling, a man who measures everything in status. In one night, all of it is stripped away when a bribery accusation surfaces, clearly engineered. The episode ends with Da-wit no longer a judge and facing an uncertain future for the first time in his life.

EP 02

Last Resort

December 6, 2025 · tvN

Out of options and out of pride, Da-wit accepts a spot in the pro bono division at O&Partners — the kind of place he would once have glanced at and kept walking. He meets his new team: idealists, oddballs, and colleagues who have chosen purpose over paycheck. The power dynamics within the firm quickly make themselves known.

EP 03

Suing God

December 13, 2025 · tvN

The team’s first major case: a 12-year-old boy in a wheelchair who wants to sue God for damages. Da-wit finds it absurd — until he doesn’t. The more he learns about young Kang-hoon and his exhausted mother, the harder it is to dismiss. A visually impaired judge adds an unexpected wrinkle to the courtroom proceedings.

EP 04

For Kang-hoon

December 13, 2025 · tvN

The Kang-hoon case reaches its climax as Da-wit argues in open court with a conviction that surprises everyone — including himself. The courtroom delivers a moment that earned the series its first ratings spike. Meanwhile, a hospital chairman with strong religious views introduces the next conflict: a case involving reproductive rights and institutional power.

EP 05

Her Name Is Kaya

December 20, 2025 · tvN

A new case arrives: Kaya, a Myanmar immigrant seeking divorce after her father-in-law assaulted her. Da-wit must navigate the intersection of immigration law and family court — territory far outside his comfort zone. Personal backstory begins to surface, connecting Da-wit’s past to the kind of work he now finds himself doing.

EP 06

First Win

December 20, 2025 · tvN

Kaya’s divorce case goes before the court — with her right to remain in Korea on the line alongside her marriage. Da-wit fights through bureaucratic and legal barriers to reach a verdict that matters. The team earns their first meaningful legal victory, and for the first time, the pro bono unit begins to feel like more than a penalty box.

EP 07

Idol Under Fire

December 27, 2025 · tvN

The team takes on a celebrity case: Elijah, a popular idol being relentlessly targeted by a cyberbullying campaign from obsessive fans and a self-styled activist named Ma Young-sook. Da-wit, who knows nothing about idol culture, has to get up to speed fast on how online harassment operates. The case brings unwanted media attention back to Da-wit personally.

EP 08

Behind the Agency

December 27, 2025 · tvN

Elijah’s case escalates as her agency CEO Cha Jin-hee — a controlling figure who treats talent like property — becomes entangled in the legal proceedings. Da-wit uncovers evidence of manipulation that goes deeper than cyberbullying alone. The episode posted the series’ highest ratings to that point, marking a clear narrative turning point for the conspiracy thread.

EP 09

The Real Target

January 3, 2026 · tvN

The series pivots to its main arc. Da-wit digs into the bribery frame-up orchestrated by Yoo Jae-bum, and what he finds is personal: his late mother’s hand was severed working at a factory owned by Yoo Jae-bum’s father — a detail that reframes the entire conspiracy. The past and present converge in ways Da-wit wasn’t prepared for.

EP 10

Dismantling It

January 3, 2026 · tvN

Da-wit pieces together the full architecture of how Yoo Jae-bum engineered his downfall — a revenge plot rooted in an old sentencing Da-wit made without knowing its consequences. He begins working from the inside to legally dismantle what was built against him. Oh Jung-in’s loyalty is tested as the firm’s internal power struggle intensifies around her.

EP 11

The Bigger Hand

January 10, 2026 · tvN

The conspiracy expands: conglomerate chairman Jang Hyun-bae — a man Da-wit once sentenced — is revealed as the financial force behind Yoo Jae-bum’s scheme. The team assembles their final legal counter-offensive. Relationships within the pro bono unit and between Da-wit and Oh Jung-in reach a critical emotional turning point.

EP 12

Where He Belongs

January 11, 2026 · tvN

The finale. Da-wit successfully exposes the conspiracy in court, clearing his name and holding both Yoo Jae-bum and Jang Hyun-bae legally accountable. But the most meaningful moment isn’t the exoneration — it’s the choice that follows. Da-wit doesn’t go back to being a judge. He stays. The series-high 10% rating reflected what audiences already knew: this was exactly how it should end.

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

The conspiracy unravels in court, not in a hallway. What makes Pro Bono’s finale satisfying is that Da-wit doesn’t win through a last-minute revelation or a dramatic confrontation outside the law — he wins by being, for the first time in his life, a genuinely good lawyer. He exposes the bribery frame-up built by Yoo Jae-bum and bankrolled by Jang Hyun-bae not through leverage or a backroom deal, but through meticulous legal work. Yoo Jae-bum’s revenge scheme — constructed around a factory injury that cost Da-wit’s mother her hand and a sentencing Da-wit made without knowing its consequences — collapses under the weight of actual evidence. Both men face legal accountability.

Clearing his name turns out to be the lesser victory. Da-wit’s exoneration is handled with relative efficiency — the drama is not interested in prolonging the legal outcome beyond what the story needs. What takes time, and what the final episode dwells on, is the question of what comes next. The path back to the judgeship is open. His reputation is restored. There is nothing stopping him from reclaiming the life that was taken from him. And he chooses not to.

He stays in pro bono — and the show treats it as the only ending that makes sense. It doesn’t frame the decision as noble self-sacrifice. It frames it as clarity. Da-wit spent twelve episodes working cases no one thought were worth taking — a child with an impossible lawsuit, an immigrant with nowhere to turn, an idol being crushed by people who were supposed to protect her. Somewhere in that work, he stopped performing justice and started doing it. The finale doesn’t sentimentalize this. It just shows a man who figured out what he was actually for.

Park Gi-ppeum and the team get their resolution too. The romance between Da-wit and Gi-ppeum reaches a meaningful conclusion — understated in the way the whole series handled warmth, without manufactured drama or a scene built around a single big confession. The pro bono team continues together, now with Da-wit not as a reluctant exile but as someone who chose to be there. The 10% series-high finale rating wasn’t a surprise. This was a drama that knew exactly what it was, and stuck to it until the end.
