Twenty-Five Twenty-One: The Friend Who Changed How You Count

Have you ever noticed that you can describe the last five years of your life entirely in terms of what went wrong? The job that fell through. The person who left. The years you feel you wasted. And then you meet someone who lived through something just as hard, and they describe it completely differently — not because they suffered less, but because they are counting a different column.

There is a moment in the first episode of Twenty-Five Twenty-One where a young man notices exactly this about a girl he has just met, says it out loud, and decides to change. It takes about twenty seconds. It is the reason people are still writing about this drama years after it aired.

What Twenty-Five Twenty-One Is About

Twenty-Five Twenty-One (스물다섯 스물하나) aired on tvN from February 12 to April 3, 2022, ran for sixteen episodes, and is available on Netflix in many regions. It was written by Kwon Do-eun and directed by Jung Ji-hyun.

The story begins in 1998, in the middle of what Koreans simply call the IMF — the financial crisis that forced South Korea to take an emergency bailout from the International Monetary Fund in late 1997. Companies that had looked permanent closed in a week. Families who had been comfortable became poor overnight. It is impossible to overstate how completely that period rearranged ordinary Korean lives, and the drama does not treat it as background scenery. It treats it as a character.

Na Hee-do (Kim Tae-ri) is a high school fencer whose school team is disbanded because of budget cuts. Baek Yi-jin (Nam Joo-hyuk) is a young man whose wealthy family has been wiped out and scattered, and who is now working several jobs at once. They meet when they both have very little. The drama follows them, and three friends around them, across more than two decades, with a present-day thread running quietly alongside.

Why It Lands Differently Than Other Coming-of-Age Dramas

Most nostalgia dramas are warm because they are looking backward at something safe. This one is warm while its characters are standing in the middle of the worst year of their lives, which is a much harder thing to pull off.

Part of it is the texture. The drama is careful with the small physical facts of 1998 and the years after — the video rental shop, the pager, the school broadcasting room, the way news arrived slowly and all at once. But the texture is not the point. The point is that these are young people being asked to build a life on ground that keeps shifting, and the show refuses to pretend that effort alone fixes that.

The other part is the friendship. This is worth saying plainly, because the marketing leads with romance: the strongest relationships in Twenty-Five Twenty-One are the ones where two people make each other better without either of them being rescued. Nobody here is saved. People are accompanied, which is a different thing and, in my experience, the thing that actually happens in real life.

The Healing Point: Two Ways to Count the Same Loss

Here is the scene.

Hee-do has just lost her team. She is not being graceful about it. She is furious, and she is already scheming about how to keep fencing anyway — a plan that is, frankly, not a very good plan. Yi-jin, who has lost considerably more than a school club, listens to her.

Then he tells her that her plan was wrong but her instinct was right. And he says the thing that stays with people: I always think only about what I've lost. She, he has noticed, thinks about what there is to gain. And he adds that he would like to start doing that himself.

What makes this land is what it is not.

It is not someone telling a sad person to cheer up. Yi-jin is not being comforted here; he is doing the noticing himself. It is not optimism, either — he does not say her situation is better than his, or that things will work out. And it is not a feeling. He does not report that he suddenly feels hopeful. He says he wants to try a different method.

That distinction matters enormously if you are going to use this in your own life. Yi-jin is describing two ways of doing arithmetic on the same event. Both of them lost something in 1998. One of them keeps a running total of the missing. The other keeps a running total of what is still available. Neither is a lie. They are just two different columns, and whichever one you keep updating is the one that grows.

Most of us keep the losses column with great discipline. We can produce it on demand, in order, with dates. The regrets. The unfairness that was never acknowledged. The thing someone said to us in a hallway fifteen years ago. We maintain that ledger carefully, and then we wonder why the years go round without moving forward.

The useful thing about this scene is that Yi-jin does not need a new personality to change columns. He needs to see it done once, by someone standing next to him, in a situation as bad as his own. That is the whole mechanism. And it means the question for the reader is not why am I like this — it is a much more practical one: whose accounting have you actually watched up close lately?

Why This Only Works Because It Goes Both Ways

If the drama had stopped there, it would be a story about a boy improved by a girl, and there are already enough of those.

What it does instead is send the benefit back in the other direction. Hee-do has the forward-facing instinct, but she is also seventeen and largely unsupported. Her mother, a news anchor consumed by her own work, is not cheering for her. Nobody in her life is treating her ambition as reasonable. Yi-jin does. He tells her, in as many words, that she gives him hope — and that he wants more for her than she is currently allowed to want for herself.

So she hands him a way of counting, and he hands her the belief that the counting is worth doing. Neither one could have manufactured their half alone.

This is the part I think is worth taking seriously, because it changes what you do on Monday. A relationship like this is not luck and it is not chemistry. It is two people who keep showing each other their actual situation — including the parts that are going badly — often enough that the exchange can happen. Yi-jin could not have borrowed Hee-do's method if she had presented herself as fine. He noticed how she counted because she counted out loud, in front of him, while things were bad.

Most of us have at least one person like this somewhere in our history. The friend who made us braver. The colleague whose way of handling setbacks we quietly copied. And most of us let those relationships go dormant, not through any falling-out, but through the ordinary attrition of not calling.

The drama is unsentimental about this. It shows how much these people gave each other, and it also shows how easily time and circumstance pull people apart even when nobody does anything wrong. That honesty is what earns the warmth.

The People You'll Remember

Na Hee-do

Played by Kim Tae-ri, who many international viewers will know from Mr. Sunshine. Hee-do is loud, tactless, relentless, and very easy to underestimate. She wants to fence at the national level, and she wants it with an appetite that makes the adults around her uncomfortable. What Kim Tae-ri does with her is remarkable: she plays a seventeen-year-old without a single moment of condescension toward her, so the ambition reads as real rather than cute. Hee-do's fear is not failure. She has failed constantly and keeps going. Her fear is being told that the wanting itself is inappropriate — which is what most of the adults in her life are telling her.

Baek Yi-jin

Played by Nam Joo-hyuk, also known for Start-Up. Yi-jin is the eldest son of a family that lost everything, which in Korean terms means he inherited the debt of holding what is left together. He works constantly. He is gentle in a way that costs him something. His arc is the quieter of the two: he is not chasing a dream so much as trying to rebuild a floor to stand on, and later, as a reporter, he runs straight into the difference between a job and a calling. He is at his best when he is noticing other people — which is exactly how the scene in episode one happens.

Go Yu-rim

Played by Kim Ji-yeon, also known as Bona. Yu-rim is the national champion, Hee-do's idol and then her rival, and the character who complicates any simple reading of the show. She is poor, she is carrying her family, and her excellence is not a joy to her — it is the only asset her household has. The friendship between her and Hee-do is one of the most interesting things in the drama precisely because it starts out as something much uglier.

Who This Is For

Watch this if you are in a stretch where the effort is not producing results yet, or if you are rebuilding something after a loss that was not your fault. Watch it if you miss having friends who knew you before you became careful.

Be warned on two counts. It is sixteen episodes of roughly seventy minutes and it takes its time; if you want plot velocity, this will frustrate you. And the ending divided viewers sharply when it aired — some people found it the most honest thing about the show, and others have not forgiven it. Go in knowing that this is a drama about a particular season of life, not a drama that promises to tie everything off neatly.

The Column You Keep Updating

Twenty seconds, in a first episode, between two people who have just met and have both been flattened by the same year. One of them is keeping a careful record of what was taken. The other is looking at what is still on the table. And the first one says, out loud, that he would like to try it her way.

He does not become a different person. He starts counting differently, and the years that follow are built on that.

You almost certainly have a losses column you could recite right now without preparation. The other column exists too. It is just the one you have not been updating.

So I would like to ask you something, and I would really like to hear the answer. Who in your life counts differently than you do — and when did you last actually talk to them? Tell me in the comments. And if there is a friendship that quietly made you better and has gone dormant, say so. Somebody reading this is sitting on the same silence and needs to see that they are not the only one.
