A song of forbidden love. A heartrending, sorrowful love song (21–30)
Run through the nightsupittsu
A Spitz song that portrays an elopement born from a forbidden love.
Knowing theirs is a relationship no one will bless, it depicts a poignant night as the couple runs off into a world for just the two of them.
Aware that they’re connected not by a destined red thread, but by something far more fragile, they still try to believe in that bond alone—an attitude that leaves you with a sense of helpless sorrow.
The track was included on the classic album Mikazuki Rock, released in September 2002, and was later used as an insert song in an anime.
It’s a work that confronts you with the purity and peril of a love you’d uphold even while turning your back on the world, prompting deep reflection.
DesireDo As Infinity
For those agonizing over a forbidden love, I want you to listen to Do As Infinity’s “Desire.” Love isn’t something you do alone, right? When you fall in love, there’s always someone else involved, and if you’re in a relationship, it’s two people sharing their feelings.
The same goes for an affair.
Even when you know it’s wrong, you keep going.
That’s not just one person’s problem—it exists because there’s someone on the other side accepting that relationship.
This song captures the unstoppable, forbidden “desire” of two people.
C.O.S.M.O.S. ~Cosmos (Autumn Cherry Blossoms)~Sandaime Jē Sōru Burazāzu fromu Eguzairu Toraibu
The lyrics express the sorrow and pain of a woman and a man who, despite being in love, cannot be together, as the woman can’t stop the impulse of falling for someone she shouldn’t love.
It’s a profoundly heartrending song that captures the complex emotions of both as they struggle between their feelings and an inescapable reality.
I just had a love sadder than anyone else’s.Flower
A song about ending an impossible love by your own choice: Flower’s “I Just Had a Sadder Love Than Anyone Else.” It’s a supportive song for people who are thinking of ending a painful relationship.
She loves him desperately, but the woman in the song lets go so that the man can choose his other love.
She lines up excuses and soothes the man who is crying and clinging to her, but isn’t it true that she wants to cry, too? She must have been waiting for the moment she’d be loved the most… It’s heartbreaking.
Street Loveindigo la End
This is a love song by indigo la End about a finished romance that must not be known by anyone.
It’s included on their 2019 album “Nureyuku Shōsetsu” (My Soaking Novel).
The song feels like a letter addressed to an ex-lover, conveying lingering attachment and frustration—though they’ve broken up, the feelings remain.
It says, no matter what happens, I want to keep loving you, but knowing those feelings won’t reach you anymore makes it all the more heartbreaking.
Depicting pure love and the painful outcome of a difficult relationship, it’s a breakup song recommended for anyone experiencing an unrequited love.
So it wasn’t me, huh.riria.
This song, Riria.’s “It Wasn’t Me, Was It.”, pierces the heart with the feelings of the so-called ‘second woman’ seen from a woman’s perspective.
When you’re having an affair or a love you can’t tell anyone about, you probably end up bottling up a lot of emotions inside, don’t you? In this song too, there are lyrics about keeping quiet and enduring—wanting to continue the relationship—even though she sensed his actions and attitude and kind of knew what was going on.
I’m sure many people will relate.
You can also feel that, even knowing the truth, she just couldn’t help loving him so much.
balladKetsumeishi
Ketsumeishi’s “Ballad,” a hugely popular affair song, is a masterpiece that brings you to tears from the very first notes of the intro.
The song portrays the aching feelings of a man who can do nothing but wait to hear from the woman he loves.
An affair is a relationship where even contacting each other feels forbidden… yet he truly wants to see her, to hold her—an unbearably bittersweet love that brings you to tears.
