Early Life and Family Background

Born in Gwanak-gu, Seoul, Lee Yujeong entered the world on June 14, 2004, into a supportive family consisting of her parents and a younger sister.

Childhood in Seoul

Initially shy and reserved, Yujeong's early years in Seoul marked the beginning of her journey toward performing arts. Her parents made a decision that would significantly shape her future - enrolling her in cheerleading during her third grade. This choice proved instrumental in helping her overcome her natural timidity.

Family influence on her career

Notably, her parents' intuitive understanding of their daughter's potential led them to encourage activities that would build her confidence. The decision to pursue cheerleading, which she continued for five years, demonstrated their commitment to nurturing their daughter's personal growth. "Cheerleading helped me to overcome my shyness because if I hadn't done that I feel I wouldn't have been able to perform in front of people," Yujeong has reflected.

Early interest in performing arts

Furthermore, her educational journey reflected her growing passion for performing arts. Her academic path included:

Attendance at Bongwon Middle School
Acceptance into the prestigious School of Performing Arts Seoul (SOPA)
Graduation from SOPA's Department of Theater and Film on February 9, 2023

Throughout her academic years, Yujeong developed particular interests that would later benefit her idol career. She honed her skills in playing piano and K-pop dance, consequently building a strong foundation for her future endeavors. Her specialization in musicals during her school years particularly showcased her early commitment to performing arts.

The combination of her family's support, educational choices, and personal determination created a solid foundation for her future in the entertainment industry. Her transition from a shy child to a confident performer exemplifies the crucial role that early experiences and family support play in shaping an artist's journey.

Produce 48 experience

In 2018, Yujeong took a bold step by participating in Mnet's survival show Produce 48, representing CNC School. Although she ranked 51st place and was eliminated in episode 8, this experience proved invaluable for her future career. The show, which brought together 96 contestants from both Korean and Japanese entertainment industries, provided her with extensive exposure to professional training and performance opportunities.

Lessons learned from survival show

Moreover, the survival show experience transformed Yujeong's perspective on her career aspirations. "When I was just a trainee, I just did what I had to do. But after being a part of a survival programme, my dream was to become a winner and I became more ambitious about my dream".

Notably, this shared experience helped them develop both professionally and personally. "I had no idea when I first came to the company that I would be debuting with the unnies, so I'm so happy. I'm even happier because it seems like our fans additionally love seeing us together again".

The competition accordingly helped Yujeong gain valuable industry exposure and build confidence in social situations. "Through doing the programme and talking with a lot of adults, I was able to experience a bigger society and that's why these days whenever I meet new people I get less nervous".
