Shinsegae Group’s Eldest Daughter Moon Seo-yoon Debuts in K-POP as “Annie” — First Case of an Idol from a Chaebol Family

Moon Seo-yoon, the eldest daughter of Shinsegae Group Chairman Jung Yoo-kyung, officially debuts on the 23rd as “Annie,” a member of ALLDAY PROJECT, the mixed-gender group under The Black Label. This marks the first time an idol originating from a chaebol family has appeared in K-POP history. On the 9th, The Black Label opened its official social media accounts and simultaneously revealed the group name, teaser videos, and the identities of all five members. ALLDAY PROJECT is the second group launched by The Black Label and has drawn attention for its mixed-gender composition. Born in 2002, Moon Seo-yoon is currently enrolled at Columbia University, a prestigious institution in the United States. She is the granddaughter of Shinsegae’s former chairman, Lee Myung-hee, and the daughter of Shinsegae International Vice President Moon Sung-wook. She does not currently hold any shares in Shinsegae. Even before her debut, she was an influencer with over 120,000 followers on Instagram. Rumors about her debut first surfaced last year when photos of her alongside trainees under The Black Label were made public. Since most of the trainees who appeared in those photos debuted as MEOVV, there were concerns that Moon Seo-yoon’s debut might be canceled. However, with her debut confirmed as part of ALLDAY PROJECT, interest in her future activities has surged. ALLDAY PROJECT consists of five members: Moon Seo-yoon (Annie), Tarzzan, Bailey, Woochan, and Youngseo. Woochan has a record of being the youngest person to advance through the preliminary rounds in Mnet’s hip-hop competition show “Show Me The Money” Season 6 in 2017. Youngseo is a trainee who appeared on JTBC’s audition program “R U Next?” in 2023. Bailey has worked as a dancer and choreographer, while Tarzzan previously debuted as a model. ALLDAY PROJECT will become the first mixed-gender K-POP group to debut in eight years, since KARD in 2017. Teddy, the founder and chief producer of The Black Label, stated that “ALLDAY PROJECT will bring a new sound to the K-POP scene with music that is truly unprecedented.”
