Dear X | TVING | 12 episodes | 2025 | Full spoilers. For plot summary and ending explained: [Dear X — Complete Review]
There is a scene near the beginning of Dear X that announces exactly what kind of show it intends to be. A woman is dying at the bottom of a rain-soaked staircase. She has been put there by her husband. She is bleeding.
Her daughter walks toward her.
The girl is perhaps ten years old. Step by step, she descends until she is standing over her mother, looking down. Then she turns to go. And as she does, her mother reaches up and grabs her ankle — murmuring, barely, a plea to be saved. The girl looks at the hand around her ankle. She shakes it off. She walks back up the stairs without looking back.
On her face, through all of this: something that is not quite grief and not quite relief — but has elements of both, and something else underneath that neither word covers. The camera does not look away. The show does not soften it with score or with the later revelation that the mother was herself violent, neglectful, capable of her own cruelties. All of that is true. None of it is offered here as explanation. The moment stands as what it is: a child who went all the way down, felt her mother’s hand on her ankle, and chose to keep walking.
This is where Dear X begins, and it is the most honest thing the show does. It tells you, immediately and without apology, that Baek A-jin — the woman this child becomes — is not going to be explained away. The damage is real. The damage is not enough. The question the series is actually asking is not how did she get this way? but something harder: given who she is, what does that tell us about the world she had to survive?
The picaresque is one of the oldest forms in narrative — the rogue’s ascent through a society she didn’t design and cannot inherit and therefore learns to exploit. Moll Flanders. Tom Jones. Patricia Highsmith’s Ripley. The archetype holds: a figure without legitimate access to resources who develops, from necessity, an extraordinary fluency in the language of the system. They learn how power works by watching it be used against them. Then they use it back.
What distinguishes Dear X is that it places a woman at the center of this form — specifically a young Korean woman navigating the entertainment industry — and refuses to sentimentalize the choice. Most versions of the female rogue eventually rest. Moll repents. Amy Dunne, the closest American analogue, achieves a domestic stability that is its own kind of trap. The genre tends to require some eventual anchoring: punishment, or domesticity, or the discovery that she had love in her all along.
Dear X doesn’t do any of that. It follows its logic to the end.
The logic begins with control.
Baek A-jin (Kim You-jung) does not want power in the abstract sense. She is not interested in wealth as comfort or status as identity. What she wants — what the series patiently demonstrates she has always wanted, from the child on the stairs to the actress accepting a Best Actress award while a documentary exposing her airs on another channel simultaneously — is the one thing her childhood never provided: the certainty that she will not be at the mercy of someone else’s decision.
Her father was violent. Her mother was a different kind of danger. The school system was a hierarchy organized by parental wealth. The entertainment industry turns women’s bodies and faces into products and then discards them when the products age. Every structure A-jin enters has a power axis, and she has learned — as a survival strategy so fundamental it has become indistinguishable from her personality — to locate that axis and position herself above it.
The show’s most unsettling insight is that this is not pathological as a strategy. It is rational. In the world Dear X depicts, everyone is positioning. The entertainment CEO weaponizes private information. The corrupt detective takes bribes. The sports agency conspires to pin a homicide on an innocent woman. The husband monitors his wife’s communications and manipulates her film scripts to trigger her trauma. A-jin’s manipulations are distinguished from everyone else’s primarily by their effectiveness.
This is the show’s central, uncomfortable argument: a sociopathic society produces sociopathic responses, and then calls the response the disease.
Kim You-jung has been, for most of her career, one of Korean drama’s most reliable presences in a particular kind of role: warm, expressive, emotionally accessible. She was the “nation’s little sister” in precisely the way that phrase implies — a performer audiences felt they knew, trusted, wanted to protect.
Dear X takes that established quality and uses it as a formal instrument.
The A-jin she plays is not warm. But she knows how warmth looks. She knows the precise angle of a concerned expression, the exact calibration of a smile that communicates openness without crossing into the vulnerability she cannot afford. What Kim You-jung does is show us a person constructing warmth from observation — the way a linguist learns a language they didn’t grow up speaking. The result is technically perfect and perceptibly hollow. To us, at least. The characters taken in by it aren’t being fooled by bad acting. They’re being fooled by excellent acting.
The moments when something else breaks through are the performance’s most dangerous passages. A-jin with Kim Jae-o (Kim Do-hoon), whose devotion to her is genuinely unconditional — the way she receives his care, not quite processing it, not quite rejecting it, carrying it like an object she doesn’t know the function of. And the moments with Heo In-gang’s grandmother, whose warmth is genuine and whose forgiveness, when A-jin confesses everything, is something A-jin didn’t plan for and cannot categorize.
These glimpses aren’t redemption arcs. They are proof that something is still there that could have been something else, under different conditions. The tragedy isn’t that A-jin is incapable of being reached. It’s that being reached has always arrived too late and from the wrong direction, and she has sealed the aperture so many times that she no longer trusts the mechanism.
The grandmother deserves her own moment here, because the show doesn’t give her enough of one.
She discovers the truth — that A-jin engineered every coincidence, manufactured every connection, used her as an instrument to access her grandson. She is told this directly, by A-jin herself. She has full information. And she forgives.
The show treats this as a plot development, a structural reversal that exonerates A-jin of one specific charge. But it is actually the show’s most radical act. More radical than any of A-jin’s manipulations, because it is not strategic. The grandmother’s forgiveness insists that A-jin is more than the sum of her operations — that some residual version of personhood survives all the sealing, and that this remainder is worth addressing.
This is not the same as saying A-jin is redeemable. It is saying that forgiveness operates independently of what the forgiven person deserves. It is a grace A-jin doesn’t know how to receive — because receiving, for her, has always meant incurring a debt.
The show places this forgiveness inside a genuine accident: the grandmother’s death was not A-jin’s doing. So even this grace is tangled with irony. The one person who chose to see past A-jin’s instrumental nature: her death is accidental, her forgiveness is real, and A-jin is left holding both facts and unable to do anything with either. The show moves on. It shouldn’t.
There are, in any serious picaresque, characters who love the protagonist without reservation. Their function is structural — they provide the warmth the central character withholds from herself — but they also raise a question the story is obligated to answer: is this enough to save her?
In Dear X, this is Kim Jae-o.
Jae-o is, in narrative terms, the show’s simplest person. He is devoted to A-jin from their high school years, through his own imprisonment, through the decade of her rise. He asks nothing from her. He accepts every role she assigns him — investigator, fixer, cover, decoy — without bargaining. When she cannot remember calling him in crisis, he comes anyway. When she is frightened and isolated in Do-hyeok’s controlled household, he is there.
The show’s answer to whether this is enough: no. Not because Jae-o’s love is insufficient, but because A-jin is not in a position to be saved by it. She receives it the way she receives Do-hyeok’s surveillance and Jun-seo’s guilt — as a force to be navigated rather than something that can be inhabited.
Jae-o’s death is the series’ most precisely placed event. It is not framed as heroic sacrifice. It is the consequence of a system in which he has been operating as A-jin’s instrument for so long that his final act — placing himself in the path of a threat to remove it — is structurally indistinguishable from every previous act. The logic of his devotion completes itself in the only way it can within the architecture she built.
This is the show’s cruelest implication: that A-jin’s relational structure doesn’t just fail to protect the people around her. It shapes the conditions of their destruction, even when — especially when — they love her.
The question of where to place Yoon Jun-seo (Kim Young-dae) is the show’s most interesting unresolved problem.
Jun-seo has known A-jin longest, has no illusions about her, and chose her anyway. His love has always been framed as love. But the show makes clear, gradually, that it has also had a dimension of self-definition. He is the person who sees her clearly and loves her anyway. That clarity, that anyway, is part of how he understands himself.
Which makes his role in the documentary — systematically gathering testimony against her, organizing a simultaneous broadcast to coincide with her award ceremony — something more complicated than betrayal or justice. It is Jun-seo finally losing faith not in A-jin but in himself as her witness. He looked at her and chose her for ten years. The documentary is his attempt to make that choice legible as a mistake.
The finale’s image: Jun-seo driving them off the edge. The car crashes, rolls, comes to rest inverted in the dark. A-jin claws toward the shattered window. And as she does, Jun-seo’s hand closes around her wrist — one last time, the dying reaching for her. She shakes it off. She climbs.
He had said they should end everything together. She didn’t contradict him. She left. Whether this is because she didn’t want to die, or because she won’t allow someone else to determine the terms of her ending, or because — and this feels closest to what the show is actually arguing — ending is simply not a category that applies to her the way it applies to other people: the show offers no answer.
What it offers instead: A-jin at the top, in the dark, in cold blue light, looking down at what she has come from. The camera pulls back, then closes in — her face, her chest, the expression forming slowly. A soundless smile, something between release and grief, that hardens, gradually, into nothing.
The girl who walked all the way down, felt her mother’s hand on her ankle, and chose to keep walking. Now above. Looking down. Still walking.
The show’s visual grammar is cold: restrained in its color temperature, precise in its compositions, reluctant to hold on faces longer than the scene requires. There are no tearful close-ups. The camera maintains the distance of someone watching through glass. This is, on one level, a tonal choice that enforces the picaresque register: we observe rather than inhabit.
But it is also, more specifically, the aesthetic of surveillance.
Everything in Dear X is being watched. A-jin watches the people she is planning to use. Do-hyeok watches A-jin. The entertainment industry watches its commodities. The audience watches all of them.
And here is what the show’s cold visual language is quietly acknowledging: we, watching A-jin from behind the glass of the camera, are inside the same structural relationship that everyone else in the story has to her. We extract value from her performance. We track her manipulations with something the criticism on this show keeps calling “professional respect” — an admiration for method that maintains protective distance from the person deploying it. We consume her damage. We use her story as entertainment.
We are, in other words, doing to A-jin exactly what the entertainment industry does to its performers, and what Do-hyeok does in his house, and what Mi-ri does from behind her office desk. The camera’s surveillance aesthetic isn’t just noir — it is the show’s tacit acknowledgment that we have entered the system. We are watchers. And like all the watchers in Dear X, we never quite understand what we’re watching.
This is the show’s most sophisticated move, and it goes largely unnoticed because the show doesn’t call attention to it. It simply builds a visual grammar that makes the audience’s position structurally identical to the positions of the characters who destroy the people they’re watching.
The picaresque traditionally requires that the rogue eventually pay. This is the genre’s implicit contract: we may follow someone amoral through a society’s margins, watching her survive through wit and will, but some accounting is required at the end. The punishment may not be simple moral justice — Moll Flanders’ repentance is conspicuously unconvincing — but it is formal. The rogue is contained.
Dear X doesn’t honor this contract. A-jin wins Best Actress. The documentary airs simultaneously. She flees — not into punishment but into absence. She is not destroyed. She is not transformed. She is simply not where anyone can find her, which is, it turns out, exactly where she has always been: at a remove from the consequences she sets in motion, standing at the top of the stairs while everything unfolds below.
And so she continues. Into whatever room she enters next. There is a next room. There always is.
A few words on what doesn’t work.
Moon Do-hyeok (Hong Jong-hyun) is structurally necessary — the logic of the story requires that A-jin encounter a controlling system she cannot subvert — but he doesn’t become a person. The locked room and institutionalized ex-wife are texture, not interior. He functions as a device at exactly the point where the drama needs him to be a character.
The ensemble of men orbiting A-jin — Jun-seo, Jae-o, In-gang, Do-hyeok — each represents a distinct relationship to her damage (witness, devotee, casualty, mirror), but the show rotates through them at a pace that prevents depth. Fewer, more fully developed, would have been sharper.
Episodes 9–12 lean on coincidence in ways the earlier episodes don’t earn. Some developments feel like the show accommodating its twelve-episode commission rather than following internal logic.
These weaknesses are real. They are also the reason Dear X, for all its formal intelligence, lands just short of the register it clearly aims for. What it achieves is significant. What it falls just short of would have been extraordinary.
Kim You-jung’s performance is what remains when the analysis is done.
The role asks her to carry, simultaneously: the strategic exterior, the blocked interior, the specific quality of someone who has learned to perform love without being able to feel it, and the almost-imperceptible register of what exists underneath — what was there before the sealing, what can still be glimpsed before it’s sealed back.
She does all of this without breaking any of it apart. The seams don’t show. The viewer is held in the same uncertainty as A-jin’s victims: unable to determine, finally, what is real. It is the most demanding kind of performance — one in which the absence of resolution is itself the craft.
Dear X is about the price of surviving in systems that treat people as commodities. A-jin pays it. She also survives. The show refuses to reconcile these facts. It holds them together because together is how they actually exist — not in the drama, but in the world outside it, where the camera is always watching and no one is quite sure what they’re seeing.
