A wonderful heartbreak song

Various K-pop breakup songs [relatability, next steps, poignancy]

I wonder how things ended up like this.

I can’t get anything done anymore…

That feeling of heartbreak is so sad and painful, isn’t it?

I think K-pop songs also have the charm of letting the emotions of a simple ballad seep deep into your heart.

That said, it’s not just bittersweet tracks—there are breakup songs in all kinds of styles, including ones that give you the courage to move forward.

When you listen to your favorite idol or a highly expressive artist’s voice, your emotions are sure to be stirred even more…!

I hope these songs help you feel understood, and even a little lighter.

Notably, he was deeply involved in the songwriting and composition, and the track is written entirely in English.

With its sophisticated mood that makes you want to listen during a nighttime drive, it’s recommended for moments when you want to think alone or spend some calm, quiet time.

Don't know youHeize

“Things you only realize after a breakup”—that’s the theme of the heartbreak song ‘널 너무 모르고 (Don’t Know You).’ It’s a 2017 hit by R&B artist Heize, known for her refined songwriting and delicate emotional expression.

Said to be drawn from real experience, the song reflects on how she didn’t truly know her lover.

Though she tried hard while wishing for happiness, she regrets the little time they actually spent together.

The intensity of the music video is a bit frightening, but perhaps it’s a way of breaking free.

You might think that a song called “Wedding” would be a happy one, right? As you keep listening, you realize it’s not about the singer’s own wedding with their lover.

It’s a heartbreakingly sad scene of attending an ex-lover’s wedding.

When you think about how they should have been the one standing next to the bride or groom, it becomes unbearable.

Jun.

K of 2PM—who debuted in 2008, is now a veteran idol, and also writes and composes—delivers the ballad with gentle, soulful emotion.

Why did I end up falling in love with you?Tōhōshinki

Released in 2008 as the eighth single, it is their 23rd single in Japan.

It reached No.

1 on the weekly Oricon chart.

Although the two are clearly drawn to each other, they can’t seem to convey their feelings well.

In the end, the woman decides to marry another man, and the song poignantly portrays the sorrow and regret of not having confessed her feelings sooner—it’s a real tearjerker.

In her solo activities in November 2025, Miyeon delivered a pop ballad steeped in the lingering afterglow of a farewell.

While she’s known for dynamic tracks with (G)I-DLE, this title song from her second solo mini-album, “MY, Lover,” layers a clear, pure vocal over the spacious interplay of delicate piano melodies and a rhythmic beat, richly portraying the call of a loved one that doesn’t fade even after parting.

The lingering memory of a name that echoes like reverb, and a sense of time that drifts between dreams and reality, are carefully woven together, conveying a moving stance of acceptance rather than actively trying to forget.

The beauty of her vocal delivery stands out against the understated accompaniment, precisely because it is stripped of excessive ornamentation.

It’s a song you’ll want to play on a long autumn night.
