balladKetsumeishi

Ketsumeishi’s “Ballad,” a hugely popular affair song, is a masterpiece that brings you to tears from the very first notes of the intro.
The song portrays the aching feelings of a man who can do nothing but wait to hear from the woman he loves.
An affair is a relationship where even contacting each other feels forbidden… yet he truly wants to see her, to hold her—an unbearably bittersweet love that brings you to tears.
Run through the nightsupittsu

A Spitz song that portrays an elopement born from a forbidden love.
Knowing theirs is a relationship no one will bless, it depicts a poignant night as the couple runs off into a world for just the two of them.
Aware that they’re connected not by a destined red thread, but by something far more fragile, they still try to believe in that bond alone—an attitude that leaves you with a sense of helpless sorrow.
The track was included on the classic album Mikazuki Rock, released in September 2002, and was later used as an insert song in an anime.
It’s a work that confronts you with the purity and peril of a love you’d uphold even while turning your back on the world, prompting deep reflection.
Dangerous Playkuriipuhaipe

A bittersweet story of forbidden love from CreepHyp.
This work candidly lays bare the emotions of being consumed by a desire you mustn’t touch.
Have you ever found yourself thinking, “Before I knew it, I’d fallen for them”? Released in January 2020, this song was also chosen as the ending theme for Fuji TV’s “Ukemen.” Sekai Kan Ozaki’s distinctive lyricism vividly portrays the guilty pleasures of infidelity and cheating.
While yearning for a deep bond, you end up settling for something superficial.
It’s sure to resonate with anyone carrying such complicated feelings.

Rather than evoking an affair, this song centers on the theme of an “unattainable love.” It poignantly expresses feelings that make you wonder whose “happiness” the title refers to.
It feels like witnessing the person you love loving someone else, and it tightens your chest.

Overwhelming love can, without us noticing, turn into invisible chains that bind the other person.
Soala conveys this painful mismatch with a heartrending voice.
It leaves you with a helpless feeling—the ironic reality that actions and affection meant for the best can end up closing the curtain on a relationship.
Released in July 2023, the song resonated with many, surpassing 20 million views on TikTok within six months.
It pierces deeply into the hearts of those who worry that their love might be a burden to the other.
The regret of not finding an answer to what you should have done—it’s truly heartbreaking.
