Moon Seo Yoon—granddaughter of Shinsegae Group matriarch Lee Myung Hee and daughter of Shinsegae Chairman Chung Yoo Kyung—is officially stepping into the spotlight as a K-pop idol.
On the 9th, THEBLACKLABEL, led by producer Teddy, unveiled the five-member co-ed group “ALLDAY PROJECT” through their official accounts. The group features powerhouse talent including Moon Seo Yoon—stage name Annie, dancer-choreographer Bailey Sok, former BigHit trainee Jo Woo Chan, and model Lee Chae Won (Tarzzan).
THEBLACKLABEL expressed confidence, stating: “The world doesn’t know ALLDAY PROJECT well yet, but we’re ready.” The accompanying videos and images showcase the group’s unique concept and visuals, with their official social media accounts already surpassing 61,000 followers and counting.
Moon Seo Yoon first sparked debut speculation last year when photos surfaced of her training alongside trainees from Teddy’s first girl group MEOVV. While MEOVV officially debuted in September 2023, Moon Seo Yoon wasn’t included in the final lineup, leaving fans curious about her future plans.
Often referred to as a fourth-generation chaebol heiress, Moon Seo Yoon has already built a significant presence online as an influencer with over 120,000 followers.
