Annie’s Early Life and Background
Born in 2002 into one of South Korea’s most powerful business dynasties, Annie is part of the prestigious 4th generation of the Samsung family. She spent much of her childhood between Seoul and New York City, growing up bilingual and bicultural. Her lineage is nothing short of remarkable, with her grandmother, Lee Myung-hee, serving as the chairwoman of Shinsegae Group, Korea’s largest distributor of luxury goods.
Lee Myung-hee herself is the youngest daughter of Lee Byung-chul, the founder of the Samsung Group. Adding to the family’s prominence, Annie’s mother, Chung Yoo-kyung, is the CEO of Shinsegae’s grocery store department. Her elite background earned her the nickname “Samsung Princess”, and she is currently enrolled at Columbia University, majoring in Art History and Visual Arts while pursuing her music career. Her younger sister is also a student at Columbia, majoring in Psychology.
Initially, her family strongly opposed her dream of becoming a singer. However, after Annie insisted she couldn’t give up, her mother, Jung Yoo-kyung, proposed a condition: if Annie was accepted into Columbia University – the alma mater of her maternal grandfather, Jung Jae-eun — she would receive full financial support.
Her mother, having seen Annie spend entire days practicing dance, didn’t believe she would actually pass. But once accepted to Columbia, Annie, as a true chaebol heir, was given full financial backing and successfully passed auditions.

I remember thinking, ‘Whatever they’re doing, I want to do that too,’”.
