[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.

You let me do as I please, and yet...arekunn

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.

Even though she knows it can never be a happy love, she can’t help liking him and wanting to see him.

The lyrics portray the pain of an affair and the anguish of being unable to escape.

This is a song written and composed by Mariya Takeuchi and provided to Akina Nakamori.

It was included on the 1986 album “CRIMSON,” and the following year Mariya Takeuchi released her own self-cover.

Instead of choosing a warm married life while living alone in the big city, the protagonist chooses a love that can never be permitted.

It portrays the poignant feelings of an office worker wandering the city at night.

“The person I fell in love with just happened to have a family” is a common story.

The frightening thing about love is that, even knowing the moment you step in you will hurt someone and be hurt yourself, you still can’t stop.

LOVE (I want to hold you)sawada kenji

Julie’s bittersweet, grown-up love song.

From the very beginning, you can tell he’s dying to hold his lover tight.

A cheating song told from a man’s perspective is unusual.

It seems the woman has a family, while the man is single.

Even though she loves him, there’s someone who loves her even more, and that makes him incredibly lonely.

Since it would be bad if her affair were exposed, the man ultimately decides to step back.

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.

A song whose vanishingly fragile, heartrending vocals tighten your chest.

Even knowing it’s almost impossible to stay together, the woman’s feelings—her wish to see the future she envisions come true—are depicted in delicate words.

The fact that she truly wants to be together but can’t express it honestly reflects her awareness that she’s hurting someone and that the relationship shouldn’t continue any further.

It’s a song that makes you think deeply about whether happiness can await a love that comes together while hurting many people.

A gem of a love song that beautifully captures the complex emotions of a woman torn by a forbidden love, with a heartrending vocal and delicate lyrics.

Kayayu from Young Skinny—a favorite among Gen Z—wrote the song, and Kanano Senritsu delivers a fragile, poignant performance.

Since its release in September 2024, it has resonated on social media, delicately depicting the turmoil of a woman who forgives even as she recognizes her partner’s lies, and the ache of memories that resurface with the changing seasons.

Its universal lyrics invite anyone struggling in love to see themselves in the story.

It’s a song that gently stays by the side of those overwhelmed by complicated feelings for someone who can’t exactly be called a good person.
