Other people’s relationshipsHitoto Yo

Hitoto Yo’s rendition of “Tanin no Kankei” feels a bit different from the usual songs about affairs.
It stays dry: whenever they meet, things heat up, and when it’s over they coolly go back to being two strangers and head their separate ways… yet you can still feel that they’ll never truly let each other go.
Kanae Kikko’s version is sultry too, but Hitoto Yo’s delivery is so intensely seductive it gives me chills.
Sayonara, baby.Kato Miria

A bittersweet love number that sings of a heart swaying between true feelings and outward facades.
It’s a track by singer-songwriter Miliyah Kato, also known for hits like “Aitai,” released in 2008 as her 13th single.
The sound is danceable yet somehow ethereal and striking.
The lyrics feel like a direct transcription of a man and woman’s exchange, making it highly relatable.
Do you leave the mystery as a mystery, or do you act to learn more and dive deeper? Love really is difficult, isn’t it?

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.
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.
StrangersMatsutōya Yumi

Shiranai Doushi, a digital-only single released by Yumi Matsutoya in 2020.
The song drew attention as the theme for the drama Lovers’ Mothers.
From the title and the lyrics, it suggests an affair, prompting listeners to read deeper into the words.
For anyone who’s experienced feelings that differ from an ordinary romance, the lyrics may strike a chord in many ways.
It’s a number that conveys the emotion of wanting to cut ties yet being unable to forget.
short-sleevedImai Miki

Anyone who is having an affair will understand all too well the pain of seeing the everyday life, the home, and the family of the person they’ve fallen in love with.
The words, “You’re not someone I mustn’t love—you’re someone who will never love me,” are unbearably heartbreaking.
I can’t sayiri

This song poignantly expresses feelings that have been quietly harbored in the heart.
The lyrics, woven in a calm, narrative tone, let the frustration of emotions that cannot be conveyed seep through.
The protagonist’s inability to accept reality is further highlighted by the softly tinted sound.
Released by iri in November 2020, the track is included on the album “Sparkle.” When you’re troubled by a love you can’t tell anyone about, this song will stay close to those feelings and gently resonate with the “words” hidden deep in your heart.
