[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 (41–50)

Pure Love RhapsodyTakeuchi Mariya

From the title, it gives off a stylish vibe that doesn’t immediately suggest adultery or cheating.

I think it conveys the feelings of someone ordinary who has fallen in love with a married man and carries that heartbreak.

You can understand the emotions of overthinking everything precisely because you’re in love.

“Falling in Love ~Fall in love~” Akiko Kobayashi (VINYL)

It’s a classic choice.

This song was used as the theme for the drama “Friday Wives,” and, like the drama, its theme is adultery.

The lyric “Because I always want your Saturday nights and Sundays” suggests that on weekends he goes home for family time, making it impossible for them to meet.

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.

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.

A song where aching sadness and faint hope intersect.

Carried by Atarayo’s vocals, it gently portrays the feelings of those tormented by unrequited love.

Even after learning the truth of a lie, the growing fear of losing the one you love is striking.

Released in January 2022 as an advance single from the album “In the Polar Night, the Moon Remains Silent,” this piece was born from a collaboration with the “Junwaidan” project, drawing on an episode selected from over 10,000 submissions.

It’s a song that stands beside anyone who wants to look forward while carrying the pain of heartbreak—recommended for moments when you want to face the complex emotions deep within your heart.
