[An Adulterous Love] A love song about a secret affair you can't tell anyone about

Dear…Nishino Kana

Kana Nishino 'Dear...(short ver.)'

This is a song by Kana Nishino that conveys the pain of bittersweet affection and unrequited love.

The melancholic piano sound evokes the feeling of softly murmuring one’s sorrow, and the expansive development of the music strikingly expresses emotions overflowing.

The lyrics, which capture the inner movements of the heart when burdened with feelings that won’t reach their destination or love that cannot be fulfilled, further emphasize the poignancy.

By also depicting the ideal of “what if these feelings had reached you,” the song renders the suffering even more vividly.

Yasuyuki Okamura – Bible 1988

It’s a slightly unusual song about the feelings of a male high school student whose female classmate is dating a 35-year-old married man.

He keeps saying, “I’d be better for you,” but she brushes him off with, “I can like whoever I want! It’s my business! Don’t be ridiculous!” Still, he can’t help thinking that being loved this much by someone else might be better than having an affair.

MISIA – Everything （Official HD Music Video）

This is one of MISIA’s best-known signature songs.

It’s a masterpiece that conveys the feeling of throwing yourself wholeheartedly at someone who won’t return your feelings.

It expresses what it means to love and how painful it can be—a love so strong it brings you to tears.

It reveals the desire for the other person to love only you.

Masaharu Fukuyama – First Love (Full ver.)

The title is “Hatsukoi,” and there’s a reason for deliberately not writing it with the standard characters “初恋.” They’re two people who each have something to protect and a place to return to.

And yet, their feelings deepen.

The frustration of being unable to move forward and unable to go back is captured well.

Even without a physical relationship, living while truly loving someone else is still a form of infidelity, isn’t it?

Yasashii Kiss Wo Shite

“Yasashii Kiss o Shite” by Dreams Come True—also well known for being featured in the drama Sand no Utsuwa (The Sand Vessel).

Many people might relate to the lyrics, “Even if it’s not rewarded, even if we’re not bound together, you are my one and only destined person,” don’t you think?

[AKASAKI] Wandering / HAIKAI (Lyric Video)

A bittersweet love story portrayed as if wandering through the city at night.

With the purity of youth and a delicate sensibility, AKASAKI sings of a heart swayed by love.

Together with a chorus that soars in the hook, it becomes a gem of a ballad that beautifully conveys guilt and yearning.

Released in April 2025, this work, though arranged simply with piano and guitar, resonates with young listeners thanks to its richly expressive vocals.

Not every love story is pure and straightforward.

This song accompanies those who wrestle with the feelings smoldering deep in their hearts and those who hesitate to find the courage to take a step forward.

LAT.43°N ～forty-three-degrees north latitude～ (from THE DREAM QUEST TOUR 2017 Live Ver.)

“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.
