[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.

If you’d like, try listening to any songs that catch your interest.

[Adulterous Love] A love song about a secret affair you can’t tell anyone about (21–30)

No PromiseChara

A song by Chara that portrays the aching feelings of a woman torn by a relationship without promises.

She longs to hold on to someone who seems about to leave, yet she can’t secure any promise for the future.

That inner conflict is delicately rendered in a whisper-like vocal.

Featured on the album “Soul Kiss,” released in July 1992, the song captures the frustration of being unable to stop loving someone—knowing it won’t be reciprocated, yet unable to let go—which perhaps only those who’ve experienced it can truly understand.

A love in which only one person suffers is something that, at some point, we probably ought to bring to an end.

This is Cocco’s shocking debut work, depicting the end of a forbidden love driven by sheer passion.

The provocative, self-destructive words that corner the other person may be a reflection of frustration and despair at a relationship with no way out.

Released in March 1997, the song is also included on the album Bougainvillea.

Because you love someone so much, you feel a twisted impulse to destroy the relationship with your own hands—knowing it’s selfish, yet unable to stop.

Perhaps such overwhelming passion comes from being consumed by a love that should never be.

Play ball!YU-KI

To mark the milestone of her 10th anniversary as a solo artist, YUKI delivered a song that evokes the beginning of a forbidden love.

Contrary to its bright, cheerleader-like sound, the worldview seems to portray a woman’s strong will as she plunges into the game of love without thinking of the consequences—“even if it’s a strikeout.” Her desperate plea for divine help conveys the pain of being unable to stop her feelings, even while knowing the relationship is forbidden.

This monumental single was released in May 2012.

Even though you know it’s wrong, this is a song that confronts your heart with a certain resolve to stake everything on this love.

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.

It’s a song that supports those suffering from an unattainable love or those who have decided to end a relationship.

Crying your heart out while listening might help you take a step toward a new love.

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.

Nevertheless, I want to do it.Ken Hirai

“Soredemoshitai” is a song by Ken Hirai that humorously portrays a forbidden relationship between a man and a woman.

In real life, even if you have a crush or someone you like, relationships aren’t something you can just forcefully seize.

But this song is different.

It sings of a very greedy woman who tries to steal a man away, yet refuses to stop loving him—depicting a strong woman with a tenacious, never-give-up spirit.

In the chorus, she practically screams out her frustration, which, interestingly, comes across as almost masculine—making it a fascinating song.
