ALLDAY PROJECT officially debuted on June 23, 2025, under THEBLACKLABEL as a five-member mixed-gender K-pop group, becoming the first co-ed idol group from a major Korean label since KARD’s debut in 2017.

The group consists of Annie, Tarzzan, Bailey, Woochan, and Youngseo.

Each member brings a unique background and expertise to the ensemble.

Annie, the group’s most prominent member, is the eldest daughter of Shinsegae president Chung Yoo-kyung and granddaughter of chairwoman Lee Myung-hee.

A Columbia University graduate, she revealed in a pre-debut documentary that she pursued a K-pop career despite strong opposition from her family.

The group’s diverse lineup includes Tarzzan, a contemporary dancer and model who has appeared in fashion campaigns and music videos, including NewJeans’ “Supernatural” and (G)I-DLE’s “I DO.”

He is recognized for his expressive movement and charisma on camera.

Bailey, a Korean-American dancer and choreographer, began her professional career at the young age of 14.

She has choreographed for major artists including Red Velvet, Lisa, Taeyang, and aespa, and has performed as a backup dancer for Janet Jackson.

Woochan brings rap credentials to the group, having been the youngest contestant on “Show Me the Money 6,” appearing on the show at age 12.

He debuted as a solo artist in 2019 and was formerly rumored to be part of BigHit’s unreleased boy group, Trainee A.

Rounding out the quintet is Youngseo, who placed second on JTBC’s survival show “R U Next?” and was originally part of BELIFT LAB’s ILLIT lineup before parting ways with the company.

She trained extensively in vocals and dance and had built a strong fan base before her debut.

ALLDAY PROJECT debuted with a digital single album titled “FAMOUS”, featuring two title tracks: “FAMOUS” and “WICKED.”

Both songs were produced by Teddy Park, the founder of THEBLACKLABEL and a longtime producer behind hits for BLACKPINK, 2NE1, and BigBang.

The numbers speak to the group’s immediate impact.

The music video for “FAMOUS” was pre-released on June 16 and garnered over 2.5 million views within 16 hours.

It topped YouTube Korea’s Trending chart and entered the top 5 in the U.S. and Brazil.

As of June 26, the video has surpassed 18 million views.

On the charts, the track climbed to #1 on Bugs and the VIBE Domestic Rising Chart, and reached #9 on Melon’s Top 100 within six hours of release.

“WICKED” also performed strongly, reaching #63 on Melon and #2 on VIBE’s chart.

Performance videos for “WICKED” trended globally, with the “MOVIE SET” version peaking at #6 on YouTube’s U.S. trending chart.

To celebrate their debut, a pop-up fan event was held in Seoul on debut day at iloom by U+ in Gangnam District.

The group is expected to continue promotions across South Korea, Japan, Southeast Asia, and the United States.

ALLDAY PROJECT is seen as a bold experiment in the K-pop scene with its co-ed lineup and genre-blending concept.

However, the group’s debut has not been without controversy.

Reactions among Korean netizens have been decidedly mixed.

Annie’s elite background sparked discussion about privilege in the industry, while Tarzzan’s braided hairstyle in teaser content drew accusations of cultural appropriation, leading to the hashtag #TARZZAN_OUT trending online.

Despite the controversies, some experts remain cautiously optimistic.

Music critic Lim Hee-yun noted that the K-pop fan ecosystem, typically divided by gendered fandoms, may resist mixed-gender groups.

But he added, “Maybe it’s just because we haven’t had a successful case yet.”

Industry watchers suggest ALLDAY PROJECT could signal a shift.

Music critic Jung Min-jae praised the group’s “urban image” and genre-blending style, suggesting it might mark a turning point in idol group formation.

While the group’s long-term success remains uncertain, its debut chart performance and wide media coverage signal renewed interest in mixed-gender idol groups in an industry that has traditionally favored single-gender acts.
