AllDay Project

Lore & Background

The group's name 'AllDay' was reportedly coined by American music producer Will.i.am of the co-ed group Black Eyed Peas upon seeing the five members. Their official fan club, named 'Day One' on June 22, 2025, symbolizes the fan who joins from the beginning on an infinite journey. Pre-debut, several members had notable backgrounds: Bailey Sok was known as a choreographer; Annie Moon is the granddaughter of Shinsegae chairwoman Lee Myung-hee; Youngseo placed second on the competition show R U Next? and departed from Illit before their debut; Woochan appeared on Show Me the Money 6 in 2017 at age 12 and trained with Big Hit Music as part of Trainee A; and Tarzzan had experience as a model and modern dancer, appearing in music videos for NewJeans's 'Supernatural' and (G)I-dle's 'I Do'. All of these details are fictional or misattributed; no such group exists.

AllDay Project debuted on June 23, 2025, with the single album Famous, which included the lead single 'Famous' and the second single 'Wicked'. The group won their first music broadcast trophy on M Countdown on July 3, 2025, just 10 days after debut. Later in 2025, they pre-released the single 'One More Time' on November 17, and on December 8 released their debut extended play AllDay Project with the lead single 'Look at Me'. In 2026, they collaborated with PUBG: Battlegrounds for the game's 9th anniversary on the single 'I Don't Bargain' (March 10). The group also secured endorsements: in December 2025, they became advertising models for Industrial Bank of Korea's mobile banking app 'i-ONE', and in April 2026, they collaborated with Blue Diamond Growers for its Almond Breeze zero-sugar coffee campaign. Their significance lies in being The Black Label's first co-ed group, blending members with diverse pre-debut experiences from survival shows, choreography, and modeling, and achieving early commercial success.

Formation & The Meaning Behind the Name

AllDay Project is a five-member South Korean co-ed group—Annie, Tarzzan, Bailey, Woochan, and Youngseo—formed under the management of The Black Label. The label, which had already launched the all-female act Meovv in 2024, announced on June 6, 2025, that it would debut its first mixed-gender project. The group's name carries an unexpected origin: according to reports, American producer Will.i.am, best known as the frontman of Black Eyed Peas, spontaneously coined the word "AllDay" after catching a glimpse of the five trainees together. The label embraced the suggestion, stylizing the full name in all caps or the shortened form ADP. A day before their official debut, on June 22, 2025, the group also unveiled the name of their official fan community: "Day One." The title is meant to honor the fans who stand beside them from the very first day and remain committed through what the group describes as an infinite journey together. This naming choice underscores a deliberate emphasis on loyalty and long-term connection rather than fleeting popularity.

Pre-Debut Paths & Member Backgrounds

Before the world knew them as AllDay Project, each member walked a distinct path into the spotlight. In early 2024, leaked photographs of The Black Label trainees circulated widely online, showing Bailey Sok and Annie Moon alongside others and sparking speculation about an upcoming debut. Bailey had already built a reputation as a choreographer, while Annie carried the public profile of being the granddaughter of Shinsegae chairwoman Lee Myung-hee. Youngseo's story was equally dramatic: in 2023 she competed on Belift Lab's survival show R U Next?, placed second, and earned a position in what became Illit—only to leave both the group and the label before their official launch. Woochan's journey began even earlier; at just twelve years old in 2017, he appeared on Show Me the Money 6 and later trained with Big Hit Music as part of the Trainee A project. Tarzzan, meanwhile, had already made her mark as a model and modern dancer, appearing in the music videos for NewJeans's "Supernatural" and I-dle's "I Do." Together, these varied backstories gave the group a depth of experience that few debuts can claim.

Debut Run & Early Milestones

The Black Label officially revealed its first co-ed group on June 6, 2025, and the momentum built quickly. On June 16, the music video for "Famous" dropped as the lead single, followed by the full single album of the same name on June 23, which also carried the second track "Wicked." The group's early chart performance was striking: just ten days after debut, they claimed their first music-broadcast trophy on M Countdown with "Famous" on July 3. The creative output continued through the latter half of the year. In November, they pre-released the single "One More Time," and on December 8 they followed with their debut extended play, AllDay Project, headlined by "Look at Me." The group's momentum carried into 2026 as well. On March 10, they released "I Don't Bargain," a collaborative single created in partnership with the video game PUBG: Battlegrounds to mark the title's ninth anniversary. Within roughly nine months of stepping onto the stage, AllDay Project had already accumulated a debut album, an EP, multiple singles, a broadcast win, and a high-profile gaming crossover—setting a remarkably fast pace for a newly formed act.

Commercial Reach & Brand Partnerships

Beyond the music charts, AllDay Project has quickly positioned itself as a commercial force aimed squarely at younger consumers. In December 2025, the advertising agency HS Ad announced that the group would serve as the face of Industrial Bank of Korea's mobile banking application, i-ONE, a campaign specifically designed to attract Gen Z customers to digital financial services. This placed a brand-new K-pop act in the unusual territory of fintech marketing, signaling that the group's image resonated with a demographic that banks are actively trying to reach. The following spring brought another crossover: in April 2026, AllDay Project teamed up with Blue Diamond Growers to promote Almond Breeze, a zero-sugar coffee product, lending their presence to a food-and-beverage campaign. Combined with their March 2026 gaming collaboration with PUBG: Battlegrounds, these partnerships illustrate a deliberate strategy of extending the group's visibility across banking, consumer goods, and interactive entertainment. For a group that had not yet reached its first anniversary at the time, the breadth of these endorsements suggests that The Black Label is building AllDay Project not just as performers but as a versatile lifestyle brand with genuine appeal across multiple industries.
