Part 1 — Why I Became a Kim Ji-won Fan Instead of Song Hye-kyo (You are here)
Two beautiful actresses. Two unforgettable love stories. But one fearless character completely changed whom I admired most.
When Descendants of the Sun aired in 2016, Song Hye-kyo and Song Joong-ki were at the center of one of the most talked-about Korean romances of the decade.
Their chemistry was undeniable. Their romantic scenes were memorable, and Gummy’s “You Are My Everything” made those moments even more emotional.
I loved the drama. I still do.
In fact, even ten years later, I sometimes return to Descendants of the Sun when I’m feeling down. There is something about its humor, romance, and lively characters that makes me feel better.
But something unexpected happened when I first watched it.
I became a Kim Ji-won fan.
Not because Song Hye-kyo was disappointing. Far from it.
It was because Kim Ji-won’s character, Yoon Myung-joo, represented something I found deeply attractive: a beautiful woman who was honest, outspoken, fearless, and determined to choose her own life.
Yoon Myung-joo Wasn’t Just Another Beautiful Woman
At first glance, Yoon Myung-joo seems to have everything.
She is a military doctor, a commissioned officer, and the daughter of a powerful army commander.
She has a respected career and a family background that could open doors for her.
But what made her interesting to me wasn’t her privilege.
It was her willingness to challenge the expectations that came with it.
Myung-joo falls in love with Seo Dae-young, played by Jin Goo. He is a dedicated soldier, but his lower military rank and different background create obstacles to their relationship.
Her father disapproves.
Dae-young repeatedly tries to distance himself from her.
And yet Myung-joo refuses to behave like a woman who should simply accept the future others have chosen.
She knows what she wants.
She isn’t afraid to say it.
And she isn’t willing to abandon the man she loves just because their relationship is inconvenient.
That was the moment I began to see Kim Ji-won differently.
She Could Have Taken the Easy Road. She Chose Love Instead.
What impressed me most was the contrast between Myung-joo’s position and her decisions.
As a commander’s daughter and an accomplished officer, she could have followed a more predictable path.
She could have avoided conflict with her father.
She could have accepted that military hierarchy and family expectations made her relationship difficult.
Instead, she fought for the right to make her own choice.
That doesn’t mean every decision she makes is perfect. Myung-joo can be stubborn, impatient, and emotionally demanding.
But those imperfections make her feel alive.
She doesn’t wait quietly for someone to decide her future.
She speaks directly, challenges people she loves, and sometimes makes situations more complicated because she refuses to hide her feelings.
For me, that combination of beauty, honesty, and boldness was irresistible.
I didn’t become her fan simply because she looked beautiful on screen. I became her fan because I admired the woman she portrayed.
Why Seo Dae-young and Yoon Myung-joo’s Romance Felt Different
The central romance between Yoo Si-jin and Kang Mo-yeon has an irresistible playful energy.
Song Joong-ki’s character is confident, witty, and constantly ready with a teasing remark.
Song Hye-kyo’s character is intelligent, independent, and more than capable of answering him.
Watching them together is genuinely entertaining.
But the relationship between Myung-joo and Dae-young carries a different emotional weight.
They already love each other.
Their biggest problem isn’t discovering their feelings. It is finding a way to stay together without sacrificing everything that matters to them.
Myung-joo wants Dae-young to stop running away.
Dae-young wants to be accepted for who he is, not merely tolerated because the commander’s daughter loves him.
That distinction matters.
Love is not the only thing at stake. So are dignity, professional identity, and personal pride.
Their relationship asks a difficult question:
Can two people protect their love without asking one of them to give up who they are?
The Ending Made Me Appreciate Their Love Even More
One of the most satisfying aspects of the final episodes is how the conflict between love and military identity develops.
Dae-young considers leaving the army, but eventually decides he wants to remain a soldier and earn the commander’s respect without abandoning his profession.
He wants to be recognized as Seo Dae-young.
Not simply as the man Yoon Myung-joo has chosen.
And Myung-joo remains the same determined woman who refuses to give up on their future.
Their story ultimately moves toward reconciliation and acceptance.
For me, that gives their romance more meaning than a simple happy ending.
Myung-joo fought for the freedom to love. Dae-young fought for the dignity to be loved as himself.
That is why their relationship stayed with me.
I Wasn’t the Only Viewer Who Remembered the Second Couple
Years after the original broadcast, viewers are still revisiting Myung-joo and Dae-young’s story.
In the comments beneath a 2025 YouTube review dedicated to the couple, one viewer said they found the secondary couple more appealing than the main couple.
Others praised Kim Ji-won’s acting and described the relationship as one of their favorite parts of the drama.
These comments don’t prove that most viewers preferred Myung-joo and Dae-young.
They do show something interesting: even years later, the couple inspires strong emotional reactions.
A separate KBS Drama Classic recap also includes viewers remembering how painful and moving their romance was.
For a drama that premiered a decade ago, that kind of continued affection is meaningful.
I Still Love Song Hye-kyo and Song Joong-ki’s Romance
My admiration for Kim Ji-won doesn’t mean I enjoyed the main couple any less.
Quite the opposite.
Yoo Si-jin and Kang Mo-yeon gave Descendants of the Sun much of its playful charm.
Their conversations, teasing, arguments, and romantic moments made the series remarkably enjoyable.
And whenever Gummy’s “You Are My Everything” played, those scenes became even harder to forget.
The two actors later married in real life in 2017, although their marriage ended in 2019.
That real-life history became another memorable part of the drama’s cultural legacy.
But when I think about which character personally captured my heart, my answer has never changed.
It is Yoon Myung-joo.
Ten Years Later, Kim Ji-won’s Character Still Stands Out
A decade has passed since Descendants of the Sun first appeared on television.
Kim Ji-won has since played many other memorable characters, including Hong Hae-in in Queen of Tears.
But whenever I think about the moment I became her fan, I return to 2016.
To the confident military doctor who refused to let her father’s position determine her future.
To the woman who could be stubborn, funny, outspoken, and deeply vulnerable.
To someone who loved fiercely but still wanted the man she loved to retain his dignity.
There are many beautiful actresses in Korean dramas.
There are also many unforgettable romantic characters.
But sometimes one character connects with your own values so strongly that you remember her long after the story ends.
For me, Yoon Myung-joo was that character.
Song Hye-kyo helped make Descendants of the Sun unforgettable. But Kim Ji-won was the actress who won my heart.
And ten years later, she still has it.
