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.

Riu Domura – Impure Love (NEOWN: THE GOLDEN Performance Video)

Riu Mura of the Impure Love Hall

A gem of a love song by Riu Domura that powerfully conveys the pain and poignancy of a love you can’t tell anyone about.

It delicately portrays the feelings of a woman who, despite having been with the one she loves, ends up feeling even more alone.

Depicting the struggle of a woman who suffers in a convenient relationship yet cannot cut off her feelings for the other person, the track was released in January 2024, later included on the album “Irregular Diary,” and has become a fan favorite performed live.

It’s a song we especially recommend to those who have been hurt by love or are currently tormented by an unrequited relationship.

I can't say it, iri

This song poignantly expresses feelings that have been quietly harbored in the heart.

The lyrics, woven in a calm, narrative tone, let the frustration of emotions that cannot be conveyed seep through.

The protagonist’s inability to accept reality is further highlighted by the softly tinted sound.

Released by iri in November 2020, the track is included on the album “Sparkle.” When you’re troubled by a love you can’t tell anyone about, this song will stay close to those feelings and gently resonate with the “words” hidden deep in your heart.

Codependence / Riu Domura (Lyric Video)

Riu Domura of Codependency

A work by Riu Domura that candidly portrays the fragility and pain of a mutually dependent relationship.

This song depicts the heartrending figure of someone who, even while understanding it isn’t true love, cannot bear the loneliness and continues a false relationship.

Even knowing they’re just convenient, they can’t break away from the joy of being needed.

You can’t help but empathize with the protagonist’s conflicted feelings.

Released in May 2019 on the EP “Escape,” this piece suggests that, even knowing you’ll end up alone, being unable to stop may be the inescapable reality of a forbidden love.

YUKI “Secret ~Teasing ver.~”

Secret YU-KI

A solo number by YUKI from former JUDY AND MARY.

It romantically sings about a secret love affair.

Even if they aren’t fated partners, when they touch, they can love each other deeply.

The woman wishes the two of them could just go off to a faraway world beyond the sky… Of course, that wish can’t come true.

The man’s lines are each sweet and poetic, with a somewhat platonic feel.

Yumi Matsutoya – Strangers (People Who Don’t Know Each Other)

Strangers by Yumi Matsutoya

Shiranai Doushi, a digital-only single released by Yumi Matsutoya in 2020.

The song drew attention as the theme for the drama Lovers’ Mothers.

From the title and the lyrics, it suggests an affair, prompting listeners to read deeper into the words.

For anyone who’s experienced feelings that differ from an ordinary romance, the lyrics may strike a chord in many ways.

It’s a number that conveys the emotion of wanting to cut ties yet being unable to forget.

THE END OF THE WORLDNoriyuki Makihara

THE END OF THE WORLD Noriyuki Makihara with lyrics

THE END OF THE WORLD by Noriyuki Makihara

This is a track from Noriyuki Makihara’s 2008 album UNDERWEAR.

Sung in a warm, gentle voice, it portrays an affectionate couple.

Their forbidden love is depicted so naturally that you wouldn’t notice anything unusual unless someone said, “It’s not a normal relationship.” The world Makihara paints feels so real that just imagining what fate awaits these lovers—who have likely managed to keep their relationship secret from everyone—makes my chest ache.

Short Sleeves – Miki Imai

Short-sleeved Imai Miki

Anyone who is having an affair will understand all too well the pain of seeing the everyday life, the home, and the family of the person they’ve fallen in love with.

The words, “You’re not someone I mustn’t love—you’re someone who will never love me,” are unbearably heartbreaking.
