timelesz' 'ONE AND ONLY': A Chosen Family

With their upcoming first album FAM, eight-member group timelesz delivers a heartfelt tribute to the concept of family—not just by blood, but by bond—with the lead track “ONE AND ONLY” (ワンアンドオンリー).

“At the heart of the song lies a simple but powerful message: out of this vast, limitless world, we found each other—and that makes us the best companions,” says the group.

True to its message, “ONE AND ONLY” shines as a pop love song layered with breezy optimism and emotional sincerity. It’s not just a song about romantic love—it’s about the love shared among friends, fans, and the entire team behind timelesz.

The decision to reintroduce themselves not as a trio, but as an eight-member group, wasn’t just a new chapter—it was a conscious act of continuation—a decision to run forward. Rather than drawing a line under their history, timelesz chose to carry it forward—transforming the musical legacy they began as Sexy Zone into something larger, more inclusive, and deeply forward-looking.

This isn’t just about preserving a name or sound—it’s about upholding the values that have always run through their work: resilience, joy, and the power of irreplaceable bonds. In choosing to grow rather than retreat, they’ve honored not only their own story, but the spirit of connection and evolution that has defined their agency across generations.

The music video mirrors this spirit perfectly. Set within a black-and-white, life-sized blueprint of a room, we see the members at ease—laughing, playing, and simply being together.

The MV begins with the original three members and gradually welcomes the five new additions, culminating in a powerful, symbolic union. Fans immediately recognized this as more than just choreography—it’s a visual metaphor for how timelesz has grown from a what ended up as a trio into a full-fledged, harmonious family of eight.

Set against a blank canvas, their colorful outfits draw the eye—highlighting each member’s individuality and reminding us that no matter the backdrop, they shine on their own terms. Then, in a striking shift, their sleek black ensembles speak to their adaptability—the ability to move confidently within the ever-evolving landscape of the music industry, without losing what makes them who they are.

The contrast between cozy, color-splashed scenes and the cool, black-jacketed dance performance highlights the group’s dual charm—sweetness and swagger, unity and individuality. The choreography, created by NOSUKE, adds a memorable flair with a hand gesture in the chorus that symbolizes the song’s title: “ONE AND ONLY.” Each member steps into the spotlight naturally, without a fixed center, proving that every individual has a place at the heart of this group.

What’s striking is the emotional response from the fans—many of whom admit they watched through tears. For those who’ve been there since the beginning, seeing the three founding members welcome five others into the “home” they built is overwhelmingly touching. For newer fans, “ONE AND ONLY” serves as a radiant invitation into the warmth of this found family. From those who have supported the group since its early days to those discovering them for the first time, the reaction is unanimous: this is something special.

Eight members of the musical group timelesz joyfully embrace each other in a playful moment, highlighting their bond and unity, set against a minimalist black-and-white background.

Because, in the endless expanse of this world, what are the odds that eight people—each with their own histories, strengths, and silent struggles—would find one another and create something this whole?

“ONE AND ONLY” is a love letter to chosen family.
To the laughter that fills shared spaces.
To the quiet strength of standing side by side.
To the miracle of becoming something more—together.

It began with three—Fuma, Shori, and So-chan: voices steady, hearts unwavering, carrying the weight of the legacy of when they were five while still daring to dream of something new. When five more stepped forward—Tera, Hara, Shino, Shuto, and Masaki—it wasn’t just a group expanding—it was a home opening its doors. And each of them brought something irreplaceable:

A voice like sunlight.
A quiet determination that grew louder with every step.
The courage to begin again.
The will to promise joy to others—even while still growing themselves.

Some had danced alone for years; others had never known what it meant to belong. But here, on this stage, surrounded by warmth and unwavering support, each member bloomed.

Every solo line, every mirrored formation, every playful glance in the MV is proof of the trust they’ve built since the start of the audition project and the future they’ve chosen. And fans—both those who have been here from the beginning and those just arriving—are part of that future too.

Because this isn’t just music.
It’s a reunion. A beginning. A family.
And in a world full of passing moments, this—this is something timeless.

And the song’s reach extends beyond the fandom. With its selection as the campaign track for ABC-MART’s adidas “CLIMACOOL” series, “ONE AND ONLY“ brings its message of unity and energy to the streets of Shibuya and beyond, showcasing the group’s evolving power and mainstream appeal.

Beyond the music and visuals, what makes “ONE AND ONLY” truly unforgettable is the emotional journey it represents—for both the members and the fans. Longtime supporters see this song as a reward for staying, a gentle affirmation that all the waiting, hoping, and cheering were worth it.

For newer fans, it feels like stumbling into something genuine and warm—an invitation into a family they didn’t know they needed. Many have found themselves unexpectedly moved by the group’s dynamic, as if watching the members grow into their roles and bond with each other has rekindled something deeply personal.

There’s also a collective sense of healing running through the reactions. Members who once stood alone are now surrounded, supported, and celebrated. The joy on their faces isn’t just performance—it’s real. And that reality hits home: this is more than just entertainment. This is the story of people finding each other, lifting each other, and choosing to walk forward together.

In a world that often feels disconnected, “ONE AND ONLY“ offers something precious—proof that chosen family is just as powerful, just as lasting.

Ultimately, “ONE AND ONLY“ isn’t just a lead track—it’s a statement. A declaration of where timelesz has been, who they are now, and where they’re going next. As fans put it best, this isn’t just a group. It’s a family. And for many, it’s home.
