You probably have feelings you’re keeping tucked away in your heart, too.

impure loveDomura Riu
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.
Nevertheless, I want to do it.Hirai Ken
“Soredemoshitai” is a song by Ken Hirai that humorously portrays a forbidden relationship between a man and a woman.
In real life, even if you have a crush or someone you like, relationships aren’t something you can just forcefully seize.
But this song is different.
It sings of a very greedy woman who tries to steal a man away, yet refuses to stop loving him—depicting a strong woman with a tenacious, never-give-up spirit.
In the chorus, she practically screams out her frustration, which, interestingly, comes across as almost masculine—making it a fascinating song.
Happy Endingback number
A song written by back number as the theme for the film “My Tomorrow, Your Yesterday.” It drew renewed attention after a certain affair scandal, and some people say it even sounds like an infidelity song.
If you’ve seen the movie, I think it comes across as a pure love song that tightens your chest, but if we define an affair as an unattainable love, then the lyrics certainly resonate in that sense as well.
The ending, where the person steps back so as not to cause trouble for the other, is one that leaves you in tears.
No PromiseChara
A song by Chara that portrays the aching feelings of a woman torn by a relationship without promises.
She longs to hold on to someone who seems about to leave, yet she can’t secure any promise for the future.
That inner conflict is delicately rendered in a whisper-like vocal.
Featured on the album “Soul Kiss,” released in July 1992, the song captures the frustration of being unable to stop loving someone—knowing it won’t be reciprocated, yet unable to let go—which perhaps only those who’ve experienced it can truly understand.
A love in which only one person suffers is something that, at some point, we probably ought to bring to an end.
IenaiSoala
A bittersweet, heart-tugging vocal captures the feelings of a woman who has fallen into a convenient relationship.
Her emotions, swaying between tender affection and regret, are woven with delicate words.
It’s striking how she knows she can’t be his “number one,” yet can’t stop herself from drowning in her feelings.
Released in August 2022 and included on the album LOVE, the song captivates with Soala’s translucent voice and a poignant piano-driven melody.
It’s a track that resonates deeply with those struggling in love that doesn’t go their way—whether long-distance or a convenient arrangement—offering comfort and profound empathy.

PretenderOfisharu Higedan Dism
Official HIGE DANDism’s “Pretender” is a beloved bittersweet love song.
For some listeners, though, it’s been a hot topic because it can sound like a “cheating song.” It’s true that the lyrics don’t include words like “I like you” or “I love you.” Maybe it’s a relationship that can’t be put into words so easily.
With that in mind, doesn’t it sound even more like a heart-wrenching unrequited love song? I think many people feel like “I’ve given up on this love from the start.” If that’s you, I really want you to listen to this song.
secretYU-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.
