[An Adulterous Love] A love song about a secret affair you can't tell anyone about

Affairs are generally considered taboo by society, but sometimes you might fall for someone without knowing they’re married.

You probably have feelings you’re keeping tucked away in your heart, too.

This article introduces songs about “affairs.”

Some songs depict people already in an affair, while others are about accepting there’s no future and choosing to part ways.

Many of these tracks express painful emotions, so you may find one that resonates with how you feel.

[Adulterous Love] A love song about a secret affair you can’t tell anyone about (41–50)

A song written by back number as the theme for the film “My Tomorrow, Your Yesterday.” It drew renewed attention after a certain affair scandal, and some people say it even sounds like an infidelity song.

If you’ve seen the movie, I think it comes across as a pure love song that tightens your chest, but if we define an affair as an unattainable love, then the lyrics certainly resonate in that sense as well.

The ending, where the person steps back so as not to cause trouble for the other, is one that leaves you in tears.

Isn’t this song told from a male perspective? It feels like a piece that conveys the unique anguish of a man who abandons his family yet cannot be with the one he loves.

It’s a song about an unattainable love, and I recommend it to women as well.

Perhaps it’s a song that can help you feel even a little more positive.

A singer-songwriter representing Gen Z, Ren, sings a song about an unattainable love.

Released in September 2021 as their first original work, it portrays a painful level of fixation—unable to sever the heart even after being betrayed.

Even knowing it’s a lie, clinging to the slightest kindness conveys a desperate feeling that makes you lose yourself.

You know you’ll never be together, yet you can’t walk away on your own.

Haven’t you ever put on a brave face to cover up those feelings that have nowhere to go?

An unflinchingly vivid major-label debut themed around the text of the law.

It tells the story of a woman who has become a party to a forbidden love, singing of her complex emotions where brazen defiance and a guilty conscience intertwine.

Released in December 2014, the song was later included on the album “anti-these.” The cover featuring Junichi Ishida also drew attention.

If it doesn’t get found out, we’re happy—but what lies beyond that? It’s a track that makes you think deeply about the harsh reality of such a precarious romance and the fragility of the human heart.

A heartrending love song about an affair that portrays a piercing, hidden longing beneath the small joys of everyday life.

Included on the March 2021 album “Pure Love Closet,” it became a talked-about track as the CM tie-in song for the audio streaming app stand.fm—one of Koresawa’s finest.

Its light pop sound is marked by a melody that somehow carries a touch of sadness.

Carefully tracing the delicate emotions of a woman who cannot leave, even while knowing where love is headed, this song reaches out to everyone struggling with complicated relationships.

Official HIGE DANDism’s “Pretender” is a beloved, bittersweet love song.

For some listeners, though, it’s been a hot topic because it can sound like a song about an affair.

It’s true that the lyrics never actually say “I like you” or “I love you.” Maybe it’s about a relationship that can’t be put into words so easily.

With that in mind, doesn’t it come across even more as a heart-wrenching unrequited love song? I think many people feel like, “I gave up on this love from the start.” If that’s you, this is a song you should definitely listen to.

FortuneHY

Speaking of HY, their refreshing songs that evoke nature are popular, but their ballads that depict slightly complicated relationships are also compelling, aren’t they? Like in this song, even relationships where the two loved each other at the beginning can reach a point where, for various reasons, they can’t honestly say “I love you” anymore.

“Fortune,” included on HY’s 2014 release HY LOVERS BEST, expresses the feeling of pretending—of being unable to genuinely say you truly like the other person now, unlike how you felt before.
