ALLDAY PROJECT has made a lot of noise in less than six months of their debut. Even BTS’ Jungkook gave a shout out to the co-ed group and shared their newly released single, One More Time with the caption, “Crazy Drunk.”
In the K-pop landscape, co-ed groups have historically struggled to make a mark. Fortunately, that was not the case with ALLDAY PROJECT (ADP). Their debut was the most explosive, to say the least. They recently won a Daesang (Grand Prize) at the KGMA 2025, just 5 months after their debut. It usually takes years for K-pop acts to win a Daesang.
Now, they are heading to release their first album in December after the record-breaking pre-release, One More Time. Before that, get to know the group and their journey so far
ALLDAY PROJECT

ALLDAY PROJECT (ADP) is a five-member co-ed group from Seoul, South Korea, under THEBLACKLABEL. They debuted on June 23, 2025, with their hit single album Famous. The group is described as a “special collaboration of five unparalleled artists.” It was created to break boundaries and bring something fresh to the music scene.
Their road to debut was different from most K-pop groups. In early June 2025, THEBLACKLABEL confirmed it was preparing to launch its first co-ed group, produced by Teddy Park. Instead of being introduced as trainees, the members were presented as already-established artists. They revealed themselves by posting photos with their contracts on their personal Instagram accounts, which immediately pulled attention to the group’s official page.
ALLDAY PROJECT debuted on June 23 with Famous, featuring the title tracks “FAMOUS” and “WICKED.” The music video for “FAMOUS” dropped a week before the debut and quickly built hype. The group found success fast—just ten days after their debut, they won their first music show trophy on M Countdown on July 3, 2025. They grabbed a second win soon after on Show! Music Core.
Since its debut, ADP has performed at major events like the SBS Gayo Daejeon Summer festival and held video call and fansign events to meet fans. On November 17, 2025, they released their first digital single, “One More Time.” The group received the Next Leader Award at The Fact Music Awards 2025 and is likely to win ‘Rookie of the Year’ at the MAMA Awards this week.

Annie, born Moon Seoyoon, is the oldest member of the co-ed group ALLDAY PROJECT under Teddy’s agency, THEBLACKLABEL. She often gets attention not only because of her talent, but also due to her privileged background. She is a fourth-generation heir of the Samsung and Shinsegae families. Despite this, she chose to pursue a career in K-pop rather than enter her family’s business world.
Her dream began at age seven after watching the music video for “Lollipop” by 2NE1 and BIGBANG. From that moment, she wanted to become an idol. However, her family was firmly against the idea. After long discussions, they agreed she could follow her dream only if she first entered an Ivy League university. Annie met this condition by getting accepted into Columbia University, which finally convinced her family to support her goal.
She joined THEBLACKLABEL as a trainee in 2018. During training, she was rumored to be part of the pre-debut lineup for the girl group MEOVV. In May 2024, it was confirmed that she would not debut with that group due to personal reasons. In June 2025, she was officially introduced as a member of ALLDAY PROJECT. The group debuted with the single album “FAMOUS” on June 23, 2025. Annie also earned a writing credit for the track “Wicked” on the album.
Outside of her career, Annie is known for her warm and lively personality. She has two retrievers named Echo and Koda. She is fluent in Korean and English, is passionate about fashion, and is close friends with well-known figures in the industry, including YGX dancer Leejung Lee.
