[Cheating Song] A forbidden love that crossed the line — infidelity song

Fake Love and HighballLET ME KNOW

LET ME KNOW – Fake Love and Highball (Official Music Video)

This song beautifully captures the ache and forbidden allure of love.

It skillfully portrays the loneliness that seeps into city nights and the emotions of surrendering to fleeting, momentary passion.

Set against a sound that’s both nostalgic and modern, the sweet, husky vocals resonate deeply.

Chosen as the theme song for the Chukyo TV drama “A Highball for the Snack-Bar Girls,” it struck a chord with many listeners.

Released in April 2024, it reached No.

2 on the iTunes Top Songs chart.

Whispering to oneself, “Just for today, please forgive me,” the protagonist gives in to false love and alcohol.

It’s a track that anyone who has spent such a bittersweet night should hear.

Wataru Ochiai – That's Unfair (Music Video)

Even knowing it won’t be reciprocated, you’re drawn to those gentle hands and that soft voice, unable to walk away…

This song vividly portrays the emotional turmoil of being trapped in such an ambiguous relationship.

Sung by Wataru Ochiai, a singer-songwriter from Osaka, it’s a track overflowing with heartache.

Released in May 2021, it’s known as one of his signature works, alongside albums like “Nonfiction,” where he has expressed a down-to-earth view of love.

The weakness and jealousy of clinging to someone even while realizing you’re being treated as a convenient option come through raw and real over an acoustic sound.

A ballad for anyone who can’t break free from a painful, forbidden love they want to end but can’t.

SLOTH / “The Line of Cheating” OFFICIAL VIDEO

Rapper SLOTH, who continues to release popular tracks.

“Uwakino Kyoukaisen” (The Line Between Cheating), included on his first album Uncensored, is, as the title suggests, a song about where the boundary of cheating lies.

The premise is that both the man and the woman are cheating, but I feel like this song packs in the truths about infidelity.

Whether “I haven’t done anything… yet” counts as cheating depends on the person.

[MV] UMEILO – High Sky

Umeiro was a four-piece guitar rock band that unfortunately disbanded in 2020.

Their song “Takairo” is an up-tempo yet bittersweet track.

The story follows a boy who learns that the girl he liked has a new boyfriend.

While he asks, “Do you really love that guy?”, deep down he realizes he was the one being toyed with.

Even so, he can’t forget her—perhaps because, somewhere inside, he still believes he might be the one she chooses.

I became someone else’s girlfriend.wacci

wacci “I Became Someone Else’s Girlfriend” Music Video

A track with a title that makes you want to quip, “What kind of declaration is that?!” It was first released as a digital-only single for four months, then included on the album Ultramarine Refrain.

Even as you think, “What kind of declaration is that, really,” tracing the lyrics gives the impression that she might still have lingering feelings for her current boyfriend.

In front of her new guy, she seems to be stretching herself a bit, and it sounds like it’s a little tough on her.

Before it gets too hard and she ends up trying to go back to where she started, she tells him to find someone new too…

It may come off as selfish, but it’s a song that leaves you with a touch of bittersweetness.

Chanmina – Call (Official Music Video)

The person I like is crazy about someone else… then why don’t you just go to them? And go ahead and get cheated on—lyrics overflowing with jealousy.

This is a track by Chanmina, a rapper who always expresses women’s feelings straightforwardly.

It’s included on her second album, “Never Grow Up,” released in 2019.

Just reading the lyrics might make it seem like it’s only about jealousy, but her wistful vocals tell a different story.

Recommended for anyone dealing with heartbreak.
