THE BOYZ Sunwoo's 'Call Me Daddy' Moment Has Fans Screaming

THE BOYZ member Sunwoo has a gift for making a single sentence go viral — and at a recent fan signing event, he outdid himself. When a fan asked what to call his photo on their phone wallpaper, Sunwoo didn't hesitate for a second: "Daddy." The moment spread across social media almost instantly, and fans have been losing their minds over it ever since.

It sounds simple, but that's part of what made it land. The word carries specific meaning in modern slang — it's used to describe someone effortlessly cool, confident, and magnetic. Coming from Sunwoo, in front of a fan, without missing a beat, it was the kind of response that makes people hit replay. More than a few fans pointed out it felt like something out of a movie — the charming idol who knows exactly what he's doing.

The Fan Sign Moment That Started It All

At the signing, a fan brought up that they had Sunwoo's photo set as their phone wallpaper. Their question was straightforward enough: when friends ask who that is, what should they say?

Sunwoo's answer was delivered with the kind of calm confidence that his fans know well. "Daddy," he said, looking directly at the fan.

The reaction was immediate. The fan reportedly couldn't contain their laughter, and the clip — once it made its way online — sparked a flood of responses. Some fans referenced Usher's Daddy's Home, suggesting Sunwoo had been listening. Others simply screamed into the void in the way that only K-pop fan communities can. The consensus was clear: Sunwoo knew exactly what he was doing, and that made it even better.

Fan signs — also known as fansigns — are small-scale events unique to the K-pop industry, typically organized by music labels as rewards for album purchases. They offer fans brief face-to-face time with their favorite artists, usually through short conversations, games, or signing sessions. For idols, they're a chance to show personality in an unscripted setting, and for fans, they're often the source of the moments that define how the world sees an artist online.

Why Sunwoo Has Always Had This Energy

Anyone who has followed THE BOYZ closely is unlikely to be surprised by this. Sunwoo — full name Kim Sun-woo, born in 2000 — joined THE BOYZ as one of its youngest members when the group debuted under Cre.Ker Entertainment in December 2017. From early on, he built a reputation for having an edge that set him apart from the group's more polished, synchronized image.

While THE BOYZ are known for their precise choreography and visual appeal, Sunwoo established himself as the member most likely to do something unexpected — in the best way. His humor is dry, his stage presence self-assured, and his interactions with fans tend to be memorable precisely because he never seems to be trying too hard. The "daddy" moment fits this pattern perfectly.

THE BOYZ, as a group, have had a strong run in recent years. They have completed major world tour stops, released multiple acclaimed mini-albums, and built a loyal international fanbase known as The B. For a group that debuted during the highly competitive mid-fourth-generation K-pop period, they have carved out a distinct identity — one where visual charisma and musical range work together. Sunwoo is a central part of that identity.

A Rapper Who Can Back It Up

Sunwoo's confidence isn't just a personality quirk. It's backed by a track record in rap that stretches back years and recently got a very public boost.

His history with the microphone predates even the fan sign that made headlines. Sunwoo previously appeared on Mnet's High School Rapper, the youth-focused rap competition that has launched some of K-pop's most respected rhymers. The appearance established him early as someone who could hold his own in a hip-hop context, not just as an idol with good timing.

That credibility paid off this year when Sunwoo was brought in as a featured artist on "KISS KISS KISS", a track performed by NOWIMYOUNG and Royal44 during the main stage rounds of Mnet's Show Me the Money 12. The song — produced by Hukky Shibaseki — ranked first on Genie Music's teen chart following its broadcast and was widely praised for its energy and performance quality.

The stage aired in Episode 10 of SMTM12, which premiered on March 19. The combination of NOWIMYOUNG's rapping, Royal44's delivery, and Sunwoo's featured contribution created a stage that reviewers called one of the episode's highlights. Sunwoo's involvement introduced him to an audience that spans beyond THE BOYZ's existing fanbase — hip-hop listeners who don't necessarily track K-pop closely took notice.

What Fans Are Saying

Online, the "daddy" clip has been making its rounds in the way that only truly well-timed moments do. Fans screenshotted the interaction, clipped the video, added captions, and ran with it in every direction. The playfulness of the response — and the directness — was what resonated most.

Many fans pointed to the moment as an example of why Sunwoo connects so naturally with people at events. Unlike more guarded answers that idols sometimes give to keep interactions professional, his response was spontaneous and genuinely funny. It did not feel like a character performance. It felt like Sunwoo being Sunwoo.

Some fans noted the specific slang context — "daddy" in the modern sense conveys someone capable, attractive, and in control of the room — and argued the answer was actually a pretty honest self-description. Others were just happy for a fan sign moment that gave them something to talk about for days.

Looking Ahead for Sunwoo and THE BOYZ

Moments like this one matter in the long run because they shape how artists are remembered between releases. A viral fan interaction can keep an artist's name in circulation for weeks, introduce them to new audiences, and remind existing fans why they fell for someone in the first place.

For Sunwoo, the fan sign moment arrives at a time when his profile is clearly growing. The SMTM12 feature demonstrated he can operate credibly outside the idol framework. The continuing success of THE BOYZ as a group gives him a strong foundation. And moments like this one show that he has the natural charisma to remain memorable even in the quietest settings.

THE BOYZ have not yet announced their next full release, but fan activity around the group remains high. If Sunwoo's recent run of attention is any indication, whatever comes next is likely to land with an audience that is already paying close attention.

For now, the fans have their answer. When someone asks who that is on your wallpaper, you know exactly what to say.
