Moon, 22, will perform under the stage name Annie as a member of ALLDAY PROJECT, a five-member co-ed group managed by The Black Label, a prominent music agency known for representing artists such as Taeyang of Big Bang and Rose of Blackpink. The group is scheduled to debut on June 23, the company announced via social media.
The move marks a rare entry of a high-profile business heir into South Korea’s intensely competitive entertainment industry. Moon is the granddaughter of Lee Myung-hee, the chairwoman of Shinsegae Group, one of South Korea’s largest retail conglomerates, and the niece of Shinsegae Vice Chairman Chung Yong-jin. Her father, Moon Sung-wook, holds several executive posts within Shinsegae affiliates.
ALLDAY PROJECT is The Black Label’s second group following the recent debut of the boy band MEOVV.
Alongside Annie, the lineup includes members known by the stage names Tarzan, Bailey, Woochan, and Youngseo. The group’s music is being produced by Teddy, a former member of 1TYM and the producer behind numerous hits for Big Bang and Blackpink.
Born in 2002, Moon is currently a student at Columbia University in New York and does not presently hold equity in Shinsegae Group. Prior to her entertainment debut, she had already cultivated a modest public profile as an influencer, with more than 70,000 followers on Instagram.
Speculation about Moon’s potential debut had circulated for months, fueled in part by images posted online showing her training alongside aspiring idols affiliated with The Black Label. Some of those trainees would go on to debut in MEOVV, leading to rumors that Moon’s own debut plans had been postponed or shelved.
