Annie (앤니)
- Full Name: Moon Seo-yoon
- English Name: Annie Moon
- Birthday: January 23, 2002
- Nationality: Korean-American
- Position: TBA
- Instagram: @anniesymoon
Annie, also known as Moon Seo Yoon, comes from one of Korea’s most influential families—she’s the granddaughter of Shinsegae Group chairwoman Lee Myung-hee and daughter of department store president Chung Yoo Kyung.
Despite her elite background, Annie has carved her own path, studying at Columbia University in New York and quietly training under THE BLACK LABEL. She was previously part of the pre-debut lineup for MEOVV but didn’t debut with the group.
Known for her calm confidence and distinctive luxury-meets-street fashion style, she often draws attention for her effortlessly polished looks—usually seen in low-rise jeans and crop tops.
Annie is also well-connected in the industry, with close ties to YGX’s Leejung Lee, CL’s sister Harin Lee, and has even met BLACKPINK and BTS’s Jungkook.
Woochan (우찬)
- Full Name: Jo Woochan
- Birthday: January 20, 2005
- Nationality: Korean
- Position: Rap, possibly all-rounder
- Instagram: @jowoochan_santa
- YouTube: @JOWOOCHAN0120
Woochan, also known as Jo Woochan, first made headlines as the youngest-ever contestant on “Show Me the Money 6” back in 2017, earning early praise for his sharp lyricism and composed stage presence.
Before joining THE BLACK LABEL, he trained under both Cube Entertainment and BIGHIT Music, and was part of the ill-fated Trainee A project that never reached debut.
Despite the setbacks, Woochan debuted as a solo rapper in 2019, steadily building his own lane with collaborations alongside artists like Pentagon’s Hui and Jeon Soyeon. Long before his rap career, he worked as a child model and commercial actor, giving him an unusually long and layered resume for someone so young.
Today, Woochan carries a quiet intensity—rooted not in hype, but in experience—and many fans see his journey as one of K-pop’s most relatable underdog stories.
Bailey (베일리)
- Full Name: Bailey Drew Sok
- Birthday: February 24, 2004
- Nationality: Korean-American
- Position: Main dancer, likely performance lead
- Instagram: @baileysok
- TikTok: @baileysok1
- YouTube: @BaileySok
Bailey Sok has been a standout in the global dance scene long before joining ALLDAY PROJECT. She began dancing at just 2 years old and gained viral recognition by the time she was 10, eventually appearing on America’s Got Talent with the all-girl crew Buns & Roses.
Over the years, she’s choreographed for major names like K/DA’s “POP/STARS” and Jackson Wang’s “CRUEL,” blending technical precision with a raw, emotional performance style that’s unmistakably her own.
In 2023, she was awarded “Dance Creator of the Year” by Adweek, solidifying her status as one of the most influential Gen Z performers in the industry.
With a powerful presence both onstage and online, Bailey is way beyond mere dancer-turned-idol. She’s a creator who brings a full artistic identity into every step.
Tarzzan (타잔)
- Full Name: Lee Chaewon
- Birthday: September 27, 2002
- Nationality: Korean
- Height: 179 cm
- Instagram: @tarzzan_boy
- MBTI: ENFP
Tarzzan, born Lee Chaewon, first entered the spotlight as a model under YGKPLUS, where his sharp visuals and confident runway presence earned him a spot in major events like Seoul Fashion Week 2022.
With a background in modern dance, trained at both Busan Arts High School and Korea National University of Arts, he brings an expressive edge to his performance style.
Tarzzan is best known for his bold, fashion-forward image—but that same boldness has sparked mixed reactions. His past styling choices, including braided hairstyles, have drawn criticism for cultural appropriation, and his social media activity has raised concerns over the public figures he followed.
Still, his unapologetic approach to self-expression makes him one of the most visually striking and talked-about members of ALLDAY PROJECT.
Youngseo (영서)
- Full Name: Lee Youngseo
- Birthday: November 13, 2005
- Nationality: Korean
- Position: Maknae
- Instagram: @youngseo
Lastly, Youngseo, the youngest member of ALLDAY PROJECT, has already lived through the intense highs and lows of the K-pop trainee world. She was a standout contestant on JTBC’s “R U Next?” and even made it into the final lineup for ILLIT, only to part ways with the group before their official debut.
Before joining THE BLACK LABEL, she trained under both SM Entertainment and Source Music, where she also trained alongside future members of NewJeans. Despite her chic visuals, fans often point out her quirky, humorous personality that sets her apart from the typical “maknae” mold.
Inspired by Billie Eilish, Youngseo embraces individuality, both in style and spirit. When she’s not on stage, she enjoys making beaded rings, collecting cat-themed items, and indulging in her favorite treat—fat macarons.
