[Adultery Songs] A Collection of Forbidden Love Songs About Unattainable Romance (71–80)
eternityZARD

ZARD’s 22nd single, Eien (Eternal).
It was used as the theme song for the drama Shitsurakuen (Lost Paradise), which deals with the subject of an extramarital affair.
I’m sure the lyrics, which seem to express feelings kept deep in one’s heart, will resonate with you.
Sakai’s gentle vocals, which somehow envelop the loneliness one must bear alone, are sure to be soothing.
In the sense of wanting to end it but being unable to, an affair is a love with no end.
Try listening to Eien while reflecting on such a love you can’t tell anyone about.
But… But… But…sonā poketto

“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.
LAT.43°N 〜forty-three degrees north latitude〜DREAMS COME TRUE

“LAT.43°N ~forty-three degrees north latitude~” is a song by DREAMS COME TRUE that seems to capture the feelings of an illicit affair.
While DREAMS COME TRUE are known for many hugely popular pop songs, they also have tracks like this that portray rather tangled relationships.
The tune evokes Japanese pop from the ’70s, and it almost sounds like something you’d hear in a daytime TV drama about infidelity.
The lyrics depict a woman trying to steal a man who already has a partner, while expressing her frustration that he won’t truly love her.
A love I can tell no one abouterica

This love song is said to have been made for a fan with an unrequited crush.
Because it was based on real feelings, it has a super realistic vibe.
They fell in love, but the other person already has a partner, and there’s no one they can talk to.
The protagonist regrets having a forbidden love and sinks into terrible self-loathing.
Still, keeping quiet forever is too painful, so they decide to take a step forward.
No matter what kind of love it is, holding it all inside is hard, isn’t it?
passing by each otherSoala

Overwhelming love can, without us noticing, turn into invisible chains that bind the other person.
Soala conveys this painful mismatch with a heartrending voice.
It leaves you with a helpless feeling—the ironic reality that actions and affection meant for the best can end up closing the curtain on a relationship.
Released in July 2023, the song resonated with many, surpassing 20 million views on TikTok within six months.
It pierces deeply into the hearts of those who worry that their love might be a burden to the other.
The regret of not finding an answer to what you should have done—it’s truly heartbreaking.
ElegyHirai Ken

This is the song “Elegy,” which was used as the theme for the film Love’s Banishment.
Love’s Banishment tells the story of a struggling novelist and a married woman who have an affair, which culminates in the woman begging the novelist to kill her—and he actually does.
“Elegy” was inspired by that married woman and was written from a woman’s perspective rather than a man’s.
Threads of the Sea of TreesCocco

“Jukai no Ito,” sung by singer-songwriter Cocco, is a forbidden adultery song that portrays an unfulfilled love set against the depths of a sea of trees.
Like tangled threads, it intricately weaves love and hate, a wish for eternity, and the pain of parting—tightening around the heart.
Released in April 1999, this track has since become a classic that continues to captivate fans.
As you listen, let yourself be immersed in its deep emotions and beautiful melody—this piece will stay close to the heart of anyone suffering from bittersweet love.
