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.

“LOVE AFFAIR ~Secret Date~” is the Southern All Stars’ 41st single, released in 1998.

“Love affair” means things like an “affair” or “tryst,” and, true to its title, this song is about an extramarital relationship.

It’s a song where you can feel the complex emotions and a man’s weakness: I love you, but I can’t throw everything away.

It’s a song by Ken Hirai that conjures up the image of a man at a bar counter, tilting his glass and hiding his true feelings as he sits beside someone gazing at their lover’s ring.

You can almost feel the protagonist’s painful frustration as he wishes they’d miss the last train, yet swallows the words instead.

Released in December 2000, the track reached No.

3 on the Oricon weekly chart and is also included on the classic album “gaining through losing.” For those entangled in a forbidden love—knowing it won’t come true yet unable to stop their growing feelings—this song may quietly keep you company.

Young Skinny’s “Maybe It Didn’t Have to Be You” is a forbidden affair song that leaves a deep scar on the heart.

It was also chosen as the opening theme for the drama “When the Intercom Rings.” In the time that passes after a breakup, the lyrics vividly portray the turmoil of blaming oneself, thinking of the other person, and wondering, “What if I had chosen differently?”—drawing listeners into its world.

Both sides hesitate to part, yet there’s no going back.

That bittersweetness flows with their gentle melodies and is sure to make your heart tremble.

“Demos…

Demos…

Demos…,” released in 2012 by the male vocal unit Sonar Pocket, is a song I’d recommend to both men and women struggling with an affair.

The lyrics, which convey the man’s feelings as he makes promises he can’t keep out of sheer honesty, alongside the words spoken by the woman, are probably the most relatable part.

Even so, the time the two share doesn’t belong to anyone else, and it makes you want to cherish it.

When you’re going through something painful, try surrendering yourself to this song.

Song for…HY

Born from keyboardist and vocalist Izumi Nakasone’s real-life experience, this memorable piece wrestles with the meaning of chance encounters and the intense, conflicted feelings for another.

Included on the album “TRUNK,” its earnest vocals, delivered alongside the piano’s beautiful timbre, resonate deeply.

A self-cover version appears on the album “STORY ~HY BEST~,” radiating a timeless charm that hasn’t faded with the years.

It’s a gentle ballad that invites empathy from those who can’t express their feelings, or who must seal them away due to circumstances such as each other’s situations or an age difference.

Sayonara, baby.Kato Miria

A bittersweet love number that sings of a heart swaying between true feelings and outward facades.

It’s a track by singer-songwriter Miliyah Kato, also known for hits like “Aitai,” released in 2008 as her 13th single.

The sound is danceable yet somehow ethereal and striking.

The lyrics feel like a direct transcription of a man and woman’s exchange, making it highly relatable.

Do you leave the mystery as a mystery, or do you act to learn more and dive deeper? Love really is difficult, isn’t it?
