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.

[AKASAKI] Wandering / HAIKAI (Lyric Video)

Wandering AKASAKI

A bittersweet love story portrayed as if wandering through the city at night.

With the purity of youth and a delicate sensibility, AKASAKI sings of a heart swayed by love.

Together with a chorus that soars in the hook, it becomes a gem of a ballad that beautifully conveys guilt and yearning.

Released in April 2025, this work, though arranged simply with piano and guitar, resonates with young listeners thanks to its richly expressive vocals.

Not every love story is pure and straightforward.

This song accompanies those who wrestle with the feelings smoldering deep in their hearts and those who hesitate to find the courage to take a step forward.

Pure Love Rhapsody Mariya Takeuchi

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)

Falling in Love ~Fall in Love~ Akiko Kobayashi

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.

LOVE AFFAIR ~Secret Date~ – Southern All Stars (Cover)

LOVE AFFAIR Southern All Stars

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.

You let me do as I please, and yet...Are-kun

You’re the one who let me fall for you / Arekun [Official Music Video]

You let me fall for you, and yet, Are-kun.

A song that resonates with the anger toward someone who only reaches out when it suits them, and the aching feeling of not being able to forget them.

In contrast to its melodic, gentle sound, the lyrics are striking for their candid, down-to-earth emotions.

Released in September 2020 and gaining buzz mainly on social media, the track is also included on Are-kun’s album “Breath.” It features the soft timbre of an acoustic guitar and an emotionally rich arrangement.

If you’re struggling with a romantic relationship, sensing your partner’s feelings drifting away but not wanting to admit it, or have been hurt by someone’s misleading behavior, you’ll likely find this deeply relatable.

A Place in the SunShogo Hamada

A Place in the Sun

A Place in the Sun Shogo Hamada

A heart-stirring ballad that portrays an illicit love affair.

Included on the album “Before the Generation of Love,” Shogo Hamada’s work gently embraces the aching feelings that slumber deep within the heart.

Since its release in March 1981, it has continued to profoundly move countless listeners.

While depicting a love in the form of an extramarital relationship, it conveys, throughout, the loneliness of hiding from prying eyes and the inner conflict of not wanting to ruin the other person’s life, giving it a depth that goes beyond a simple love song.

It is a gem of a track that quietly stands by the hearts of adults who carry the weight of family, work, and life itself.

Pure White Maiko Fujita

This is a work by Maiko Fujita that portrays a forbidden love that reason cannot suppress, using the motif of a white flower blooming in the dark night.

Set in a foggy city bathed in moonlight, it delicately weaves the precarious and heartrending fate of a man and a woman burdened with loneliness.

Released in March 2025, it was included on the album “Unrequited Love” as the 2nd anniversary song for the smartphone romance game Ikemen Villains: A Dark Love That Blooms at Night.

It is a quiet companion for those who are in a love they cannot tell anyone about, or who have once burned with the purity of love.
