Why Her? Ending Explained: The Two Leads' Final Choice

"Why Her?" ended its 16-episode run on SBS — one of Korea's three major terrestrial broadcasters — on July 23, 2022, closing out the story of a ruthless lawyer clawing her way back from ruin and the law student who never leaves her side.

Years later, English-language forums still ask the same question: what exactly did Oh Soo-jae and Gong Chan choose, and why does the show end so quietly instead of with an arrest scene or a wedding? The answer is less in episode 16 itself and more in how the whole season was built to lead there.

What actually happens in the last two episodes

Episode 16 resolves three things almost at once. A disciplinary hearing meant to end Soo-jae's career instead becomes the venue where she proves TK Law Firm chairman Choi Tae-guk killed two people. Gong Chan's years-old false murder confession is thrown out. Cornered, Choi Tae-guk takes his own life in his office after one last phone call to Soo-jae.

The story then jumps forward. Soo-jae opens a small law firm of her own and keeps teaching as an adjunct professor; Gong Chan, now a licensed attorney, is with her. Neither beat plays as a twist — both were set up in earlier episodes.

How Soo-jae ended up teaching law students instead of running a firm

The series opens with Soo-jae as TK Law Firm's youngest partner, the associate junior lawyers are told to imitate. She loses that footing early, demoted to run the firm's legal-aid clinic after uncovering wrongdoing inside the firm she works for.

The clinic is what puts her in a classroom instead of a corner office, and it's where she meets Gong Chan, a first-year law student with a hidden connection to the case that eventually unravels the chairman. Everything in the finale grows out of that demotion.

There is no source webtoon to check this ending against

Many Korean legal and mystery dramas of the past decade began as a webtoon or novel, which lets international viewers read a season's ending back into a manhwa that predates it. "Why Her?" cannot be checked that way.

The script was an original screenplay by Kim Ji-eun, a first-time writer, with no prior webtoon or novel — a detail confirmed by multiple Korean entertainment outlets when the show premiered. Every structural choice in the finale, including its restraint, was built for this show alone.

That matters for how to read the ending: the logic behind Soo-jae's and Gong Chan's final choices lives entirely inside the 16 aired episodes, in the callbacks and mirrored characters the writer set up herself.

Two murders, one pattern: why the writer didn't stop at one mystery

The finale resolves two killings, not one. Jeon Na-jung was murdered years earlier after witnessing an assault by a group of powerful men; Choi Tae-guk killed her to protect himself, and the crime was pinned on Gong Chan. Park So-young, a hostess-bar worker pregnant with Choi Tae-guk's child, was pushed to her death much more recently.

The two cases share an origin: Na-jung died because she crossed paths with the survivor of an assault the same men committed, and covering that up is what taught the group they could keep getting away with it. One cover-up became a habit, and the habit produced a second body.

Running two murders in parallel lets the show argue something specific: Choi Tae-guk's cruelty isn't a single lapse from years ago — it is a pattern he never stopped repeating. Soo-jae spends the season defending a firm built on that pattern before she can dismantle it.

Why the chairman works better as a mirror than as a villain

Choi Tae-guk isn't written as a cartoonish antagonist. He is Soo-jae's mentor at TK Law Firm, the man whose ruthlessness she was trained to imitate — and, unknown to her for most of the series, the person who hid her own child from her.

Recappers who followed the season closely have described him functioning as a dark mirror for Soo-jae: proof of what "success at any cost" looks like after thirty more years of practice. Her choice to expose him in the finale is also a choice about which version of herself she refuses to become.

How Soo-jae's missing daughter turns the case personal

Midway through the series, Soo-jae learns that Choi Jae-yi — the daughter she was told had died at birth — is alive, and that Choi Tae-guk hid the child from her for years using a faked stillbirth. Jae-yi dies in a traffic accident soon after mother and daughter reconnect.

Jae-yi's father, Choi Joo-wan, publicly blames Soo-jae for the accident. His father seizes on that grief and calls in the prosecutors and judges he controls to open a disbarment hearing — turning a private tragedy into the very legal proceeding Soo-jae uses, in the finale, to take him down.

Whose testimony actually brings the firm down

The chairman isn't exposed by an outside investigator. He's exposed by people inside his own circle who decide the cost of staying loyal is higher than the cost of turning on him.

• Ha Il-gu, his longtime secretary, testifies once he realizes Choi Tae-guk plans to make him the fall guy.
• Choi Yoon-sang, the chairman's own younger son, hands Soo-jae documents his father kept as insurance against his two closest allies.
• A police officer admits, under questioning, that Gong Chan's original confession was coerced.

Each piece of testimony comes from someone the chairman assumed would stay silent. The finale's argument is that this kind of power collapses from the inside once the people protecting it stop being protected in return.

The line Soo-jae writes on the blackboard twice

In the pilot, Soo-jae writes on a classroom blackboard, "I will never send my client to jail" — a boast from a lawyer who treats winning as the only value. In the finale, arriving late to her first class of a new semester, she writes the same line again, facing a new set of students.

The words haven't changed, but what they mean has. Reused this way, the line becomes the show's shorthand for its own thesis: Soo-jae's competence was never the problem, only what she was using it for. A top student who could have interned at TK Law Firm instead chooses Soo-jae's small practice, passing that same shift to the next generation.

Why the finale ends in the rain instead of a wedding

The romance closes on one wordless scene: Soo-jae caught without an umbrella in a downpour, and Gong Chan arriving with one — a callback to an earlier episode where the gesture went the other way. There's no proposal, no time jump to a wedding, no declaration.

Lead actress Seo Hyun-jin described her hopes for the character in similar terms after the finale aired, saying she wanted Soo-jae to be "more happy and honest to herself" going forward — a life still being lived, not a plot closed with a bow.

The restraint reads as a choice, not an omission: a bigger romantic gesture would have overstated a relationship the show always treated as secondary to Soo-jae's reckoning with power.

What the finale leaves unresolved

Choi Tae-guk was only one part of a three-man network that also included a biotech company chairman and a sitting lawmaker, both of whom helped cover up the original assault and murder. The finale focuses almost entirely on Choi Tae-guk; his two associates and their families are not shown facing comparable consequences.

Some viewers flagged this as the finale's biggest gap, arguing the writer had built a wider conspiracy than the ending actually punished. It's a fair reading — SBS did not extend the story to address it, and no sequel or spin-off has been announced.
