Moon Seo-yoon, Daughter of Shinsegae Group Chairman, Makes Official Debut as Part of K-Pop Mixed-Gender Group “ALLDAY PROJECT”

Moon Seo-yoon, the granddaughter of Shinsegae Group Chairman Lee Myung-hee and daughter of Chairman Jung Yoo-kyung, is debuting as a K-Pop idol. The Double Black Label announced on the 9th that it is launching the new mixed-gender group “ALLDAY PROJECT,” with the group set to make its official debut on the 23rd. ALLDAY PROJECT is a mixed-gender group composed of five members: Moon Seo-yoon (Annie), Tarzzan, Bailey, Woochan, and Youngseo. The members range in age from 19 to 23 years old, with Moon Seo-yoon, born in 2002, being the oldest. She was previously a trainee at YG Entertainment, but despite multiple rumors about her K-Pop group debut, it never came to pass. Her debut now appears to fulfill that long-held dream. The most notable feature of this group is its significant meaning in K-Pop history. ALLDAY PROJECT is the first mixed-gender group to appear in 8 years since KARD debuted in 2017. Although mixed-gender groups such as Lula, Tutu, and Jam were popular in the 1990s, the domestic music industry reorganized around male and female idol structures after boy and girl groups like H.O.T. and S.E.S. achieved widespread success in 1996, making mixed-gender groups rare for a long time. ALLDAY PROJECT is the second group launched by The Double Black Label, which already has BLACKPINK, LE SSERAFIM’s Rosé, BIGBANG’s Taeyang, and the girl group Meovv under its roster. The Double Black Label was founded in 2016 by Teddy (Park Hong-jun), the former CEO of YG Entertainment, who oversees the music production for all groups he leads. Teddy was responsible for conceiving the concept and composing the music for BLACKPINK and was named one of “The 50 Greatest Producers of the 21st Century” by Billboard in 2021. Moon Seo-yoon’s debut creates a new phenomenon as a chaebol figure enters the K-Pop idol industry. She also becomes the first K-Pop “chaebol idol” with an education background from an Ivy League institution. Her younger brother, Moon Seo-jin, shared the announcement of ALLDAY PROJECT’s debut on social media to express the family’s support. The Double Black Label plans to release various teaser content ahead of the official debut on the 23rd. With its experience producing the soundtrack for KPop Demon Hunters, industry attention is focused on how The Double Black Label’s deep expertise in Korean culture and music production will be applied to this new mixed-gender group.
