Absolute relationshipakai kouen

Akaiko-en – Absolute Relationship (MV Full Ver.) [Theme Song for Fuji TV Saturday Drama “Lost Days”]
Absolute relationshipakai kouen

This is the song ‘Zettaiteki na Kankei’ (‘Absolute Relationship’), which was used as the theme for the drama Lost Days.

It was written specifically for this drama.

Its brevity—just 100 seconds—also became a talking point.

While it can be seen less as a love song and more as a track themed around “secrets,” I think it’s perfect for people involved in a romance they can’t tell anyone about.

The sound has a catchy vibe yet carries a certain tension, and the lyrics depict a world where you act so that no one finds out.

Perhaps there’s something in it that resonates with the relationship between the two of you.

sunflowerSEKAI NO OWARI

The protagonist, who had been living in a dark world, ends up meeting “you,” someone dazzling like the sun—the beginning of a forbidden love as sung by SEKAI NO OWARI.

Listening to this song, you can feel that bittersweet thrill of knowing the person is off-limits, yet realizing thanks to them your world is starting to gain color.

Maybe it’s precisely because the melody is light and pop that it tightens your chest even more.

This track is included on the acclaimed album “Lip,” which topped the Oricon charts in February 2019.

It’s a song that gently stays with you in that helpless rush of feelings at the moment you fall in love, even when you know it won’t be returned.

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.

It’s a song by Ken Hirai that conjures up the image of a man at a bar counter, tilting his glass and hiding his true feelings as he sits beside someone gazing at their lover’s ring.

You can almost feel the protagonist’s painful frustration as he wishes they’d miss the last train, yet swallows the words instead.

Released in December 2000, the track reached No.

3 on the Oricon weekly chart and is also included on the classic album “gaining through losing.” For those entangled in a forbidden love—knowing it won’t come true yet unable to stop their growing feelings—this song may quietly keep you company.

Dear…Nishino Kana

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

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.

Through countless nightsCHEMISTRY

It’s a CHEMISTRY track that puts an aching poignancy front and center, depicting someone who keeps singing feelings that will never reach their destination.

The distinctive, floating sound seems to express a sense of emotional instability.

With its simple arrangement—wavering organ tones and vocals—the message embedded in the singing and lyrics feels all the more emphasized.

It powerfully conveys the pain of thinking about a beloved person who has gone away, and of piling up unreachable wishes within oneself.

This song captures the inner conflict of a woman who can’t bring herself to hate him, even though she knows his heart is drifting away.

The title “WRONG” means “mistake.” Many people experiencing a love that likely won’t come true will painfully understand the feeling of wanting to believe that their feelings for him are a mistake, trying to convince themselves of it.

You can really feel the heartache of the moment she realizes his true feelings.

This song was also chosen as the theme for the drama “When a Marriage Breaks.”
