Through countless nightsCHEMISTRY

It’s a CHEMISTRY track that puts an aching poignancy front and center, depicting someone who keeps singing feelings that will never reach their destination.
The distinctive, floating sound seems to express a sense of emotional instability.
With its simple arrangement—wavering organ tones and vocals—the message embedded in the singing and lyrics feels all the more emphasized.
It powerfully conveys the pain of thinking about a beloved person who has gone away, and of piling up unreachable wishes within oneself.
Adam and Evego!go!vanillas

A song that poignantly portrays a love story where one feels on the verge of drowning in sweet words whispered by the ear.
It offers a modern interpretation of the Old Testament’s Adam and Eve, expressing the turmoil of a man and woman who fall into a forbidden love through go!go!vanillas’ characteristically delicate sound.
Though the relationship is morally impermissible, the heart is captivated by the beauty of the moment, intertwining with a dreamlike melody.
Released in March 2021 as a track on the album “PANDORA,” the piece debuted alongside a music video directed by Takuro Okubo.
Its emotional storytelling harmonizes beautifully with the band’s signature, striking guitar riffs.
Recommended for those who find themselves wavering amid complex emotions.
Stray HeartsInaba Hiroshi

Koshi Inaba, also known as the vocalist of B’z, is a singer-songwriter whose powerful voice captivates many listeners.
His seventh digital-only single, “Stray Hearts,” was written as the theme song for the TV drama “Even If You Don’t Do It.” The lyrics, which portray the feelings of being unable to part despite knowing it’s a forbidden love, tighten the chest with anxiety about an ending that may come someday.
It’s a passionate rock tune distinguished by a rock sound that puts piano and strings at the forefront.
The Talent for LoveKawamoto Makoto

Ai no Sainou (The Talent for Love) is Makoto Kawamoto’s debut single, released in 1996, with composition by Yasuyuki Okamura.
The song expresses the feelings of a woman who revels not in suffering or pain, but in the thrill of a forbidden love.
Just listening to it makes your heart race.
wordsAimer

A song that captures the feelings of a woman suffering from parting with her beloved.
Written by singer-songwriter Mao Abe, also known for the classic “I Want to Be Your Girlfriend,” the track is titled “words.” It was included on Aimer’s 2013 album After Dark.
The dark, tense melody, which seems to express a woman’s profound sorrow, perfectly accompanies those inescapable emotions—like the moment you’re betrayed by the words “You’re the only one,” or when you wonder, “Why can’t I hate you even though you’re so cruel?”
Unfinished MelodyYaita Hitomi

It’s a heart-wrenching love song that pleads to be chosen.
This piece by Hitomi Yaida—also known for hits like “My Sweet Darlin’” and “Look Back Again”—was released in 2002 as her eighth single.
It’s a mid-tempo rock number with a cool, chilly atmosphere, and the melody and vocals accentuate that coolness.
It pairs well with the sorrowful worldview of the lyrics.
A room feels so much bigger when the person you were with is no longer there, doesn’t it?
WRONGyukaDD

This song captures the inner conflict of a woman who can’t bring herself to hate him, even though she knows his heart is drifting away.
The title “WRONG” means “mistake.” Many people experiencing a love that likely won’t come true will painfully understand the feeling of wanting to believe that their feelings for him are a mistake, trying to convince themselves of it.
You can really feel the heartache of the moment she realizes his true feelings.
This song was also chosen as the theme for the drama “When a Marriage Breaks.”
