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.
We Who You Don’t Knowchay feat. Crystal Kay

It was the theme song for the drama “Anata ni wa Watasanai,” starring Yoshino Kimura.
The song opens with a shocking phrase.
It leaves the impression that a serious woman can change this much when she falls in love.
Deep in a woman’s heart, there is a box that has never been touched before.
That box holds tremendous energy, turning a gentle woman into a passionate person.
A love story with no return.sonā poketto

A song released in 2015 by the three-member music unit Sonar Pocket.
It was created as a heartbreak song following their pure love ballad “Sukidayo.
~100 Times of Regret~,” which swept various digital distribution awards in 2011.
In love, timing is everything.
Many of us have probably thought, “If only I had fallen for them sooner, we might have ended up together.” Because time can’t be turned back, this song makes you want to treasure each encounter in the moment and not put off expressing your feelings.
It also reminds us that having the courage not to step into a forbidden relationship is important.
First LoveFukuyama Masaharu

Hatsukoi (First Love) was Masaharu Fukuyama’s first single in a minor key.
It was used as the CM song for REGZA, the LCD TV brand in which he also appeared.
First love tends to be etched in our minds as a beautiful memory.
Even when both you and the other person have families you must protect, the feeling of being unable to forget your first love may linger in many hearts.
It’s a relationship with your first love where you can be neither friends nor lovers again.
Precisely because life can’t be rewound, this is a song that makes you want to cherish each and every love.
Adult code of conductShiina Ringo

Produced by Ringo Sheena and selected as the theme song for the TBS drama “Quartet,” this work is a forbidden adultery song that portrays the secrets and inner conflicts carried by two lovers.
The heavier responsibilities that come with adulthood, and the loneliness of living with feelings you can’t confide to anyone, are vividly reflected in its striking lyrics.
Sung by the unit “Doughnuts Hole,” formed by the drama’s four lead actors, the song aligns beautifully with the story and is sure to resonate with people of all generations struggling with love.
Even if the romance is unattainable, please take time to savor this track, which listens to and stays close to those feelings.

“ALWAYS,” known as one of Mika Nakashima’s signature songs, captivates with lyrics themed around deep love and heartache, seamlessly blended with her delicate emotional expression.
The profound compassion for a loved one and the sorrow for what’s slipping away truly strike a chord.
Released on January 20, 2010, and featured as the theme song for the film “Sayonara Itsuka,” this track is one you’ll want to hear especially if you’re struggling with love.
It gently stays close to the hearts of those suffering from unrequited feelings.

FortuneHY

Speaking of HY, their refreshing songs that evoke nature are popular, but their ballads that depict slightly complicated relationships are also compelling, aren’t they? Like in this song, even relationships where the two loved each other at the beginning can reach a point where, for various reasons, they can’t honestly say “I love you” anymore.
“Fortune,” included on HY’s 2014 release HY LOVERS BEST, expresses the feeling of pretending—of being unable to genuinely say you truly like the other person now, unlike how you felt before.
