a burned-out plainCocco

There are songs that, while not necessarily written with infidelity in mind, sound that way to those involved and draw them in emotionally.
Cocco’s “Yakenohara” is surely one of those songs.
Released in 2001 as her 11th single, it’s also one of her more popular numbers.
It’s a track that powerfully conveys the ache of a sad love—an unfulfilled romance and feelings that never reach their destination—and surely many listeners find their chests tighten when they hear it.
Crimson Heat HazeB’z
A track included on B’z’s sixth album, RUN, released in 1992.
Opening with Takahiro Matsumoto’s soulful, tear-jerking guitar, the song is a number about an extramarital affair between two married people—something we hear about more often in recent years.
The lyrics strikingly depict the unstoppable impulse that draws the two closer together, born from subtle frays in the feelings they each have toward their partners in everyday life.
With a bittersweet yet beautiful atmosphere that perfectly matches the lyrical content, the song pulls you into its world, and despite being an album track, it has maintained enduring popularity.

Don’t you find that songs written by men from a woman’s perspective can be surprisingly on target and hit you where it hurts? Masaharu Fukuyama’s 2009 release “Nagareboshi” depicts the inner turmoil of a protagonist who’s trying not to fall in love.
There are men everywhere who, despite being married or already having a girlfriend, act in a suggestive, leading way.
By the time you start telling yourself “I mustn’t fall for him” or “There’s no way I’ll get serious,” you’re already in too deep.
Even so, it’s a song many of us relate to, portraying a heroine who’s determined to face reality and avoid getting hurt—trying not to break anything or be a burden on anyone, all while being bravely steadfast.
A Two-Hour Vacation (featuring Sheena Ringo)Utada Hikaru

This collaboration between Hikaru Utada and Ringo Sheena is a track distinguished by the beautiful tones of ’60s-style guitar arpeggios and strings.
The contrast between Utada’s gentle vocals and Sheena’s harder-edged delivery deftly expresses the precarious interplay of the ordinary and the extraordinary in romantic relationships.
There’s also a subtly sapphic atmosphere, reflecting a heightened awareness of gender issues.
The space-set music video directed by Yuichi Kodama drew considerable attention as well.
It’s a song perfect for adult women—one you’ll want to play when you’re in the mood to spend a special moment.

He wrote “qualia” as the theme song for the romance drama Sister.
The song portrays feelings of hatred toward someone who won’t look your way, along with the inner turmoil of still being unable to dislike them.
It ties in with the drama’s story, conveying a very realistic state of mind.
That said, the melody and vocals have a refreshing feel, so you may find yourself soothed as you listen.

It was also chosen as the opening theme for the drama “When the Intercom Rings.” In the time that passes after a breakup, the lyrics vividly portray the turmoil of blaming oneself, thinking of the other person, and wondering, “What if I had chosen differently?”—drawing listeners into its world.
Both sides hesitate to part, yet there’s no going back.
That bittersweetness flows with their gentle melodies and is sure to make your heart tremble.
