Bokuwa Kiminokotoga Sukidakedo Kimiwa Bokuo Betsuni Sukijyanaimitai

A quintessential back number love song that distills the pain of unrequited love right into its title.

It’s a track from the album “Chandelier,” released in December 2015.

With plain, direct lyrics, it draws the gap between a wholehearted devotion to someone and the reality that those feelings don’t reach them.

Even while realizing that your world revolves around that person, you’re not someone special to them—that frustrating ache hits hard.

It’s a song you’ll want to hear if you’re in a one-sided love or struggling because the person you like won’t look your way.

back number – Yellow

This is a poignant ballad that overlays feelings for an unattainable person—and emotions that can neither move forward nor turn back—onto the colors of a traffic light.

It was released in September 2021 as the 21st single.

Since it was written as the theme song for ABEMA’s dating show “Koi to Ookami ni wa Damasarenai” (Don’t Be Fooled by the Wolf), many of you have probably heard it.

It was later included on the album “Humor.” The delicate nuances of a heart that becomes unable to act the more it longs for someone—so vividly portrayed by Iyori Shimizu—come through with aching clarity.

Takeshi Kobayashi also participated in the arrangement, and the tender, beautiful sound is truly heart-wrenching.

When you feel left behind, listening to it will gently stay by your side.

On nights when you’re timid about love, why not soak in it quietly, alone?

back number – Old Fashion (full)

Released in November 2018 as the 19th single, this song was newly written as the theme for the TBS Friday drama “A Big Love: With You Who Forget Me.” It’s a gem of a love song that layers the miracle of an unexpected encounter and the memories that remain after parting with a lover onto the small, everyday motif of a donut.

The lyrics heighten the poignancy as they shift from a complementary relationship—“you had everything I was missing”—to a sense of loss recounted in the past tense.

Set at a mid-tempo pace, the melody should be easy to sing at karaoke!

Set against the backdrop of a summer festival, this bittersweet love song portrays the feelings of a man who can’t bring himself to confess his love.

Released in 2012 as the sixth single, it was also included on the third album “blues” and the best-of collection “Encore.” Chosen as the opening theme for TBS’s COUNT DOWN TV in July 2012, it reached many listeners.

Wanting to hold hands but hesitating, wanting to say “I like you” but unable to put it into words—the song is filled with that poignant frustration, evoking the faint, youthful crushes many experienced in their school days.

Amid the lively bustle of the festival, quiet emotions surface; this is a track that resonates with the sweet, fleeting moments of love.

It sings that true happiness in life comes not from social success or status, but from having someone important by your side.

This heartwarming piece was released in May 2012 as their fifth single and became widely known as the theme song for the drama “Soup Curry.” Happiness is often hidden in everyday routines we take for granted.

Why not listen to this song and rediscover the warmth of the person right next to you?

Back Number – Supporting Actress Syndrome 2 [Chandelier] #8

This is a song by back number that portrays the inner conflict of a woman who, even while realizing she’s being treated as someone to fill a void in the other person’s heart, desperately tries to be liked by him.

The frustration she feels toward herself for accepting a man who shows he’s married right up to the very last moment, and for trying to play the role of the woman he prefers, might be a common emotion among women involved in affairs.

This is what it means to be in a relationship where no one can be happy.

You can’t control the feeling of falling in love, but don’t you think a forbidden love is something that shouldn’t be started in the first place?

back number – Mabataki (full)

An inspiring song by back number that deeply contemplates the essence of happiness.

Released in December 2017 as the theme song for the film “The 8-Year Engagement,” it became a major hit, reaching No.

5 on the Oricon Weekly Singles Chart.

The lyrics, which sing that true happiness lies in holding an umbrella for someone precious to you, gently warm the heart.

For lovers separated by distance or those who can’t meet easily, it may especially stir a strong desire to “protect the other person” and “be by their side,” don’t you think?
