An Unexpected Start to Stardom

Kim Se-jeong’s journey began unexpectedly in 2013 when she mistakenly attended a Jellyfish Entertainment audition instead of the FNC audition she had planned to go to. Competing against 3,000 applicants, she was accepted, marking the beginning of her career. Reflecting on the experience, Kim said she admired the company’s talented artists and felt fortunate about the chance she had stumbled upon.

Kim Se-jeong’s big break came in 2016 through Mnet’s Produce 101. Her strong vocals, engaging personality, and charm quickly won public attention. Finishing second in the final, she debuted as a member of the project girl group I.O.I, gaining center-stage recognition and establishing herself in the competitive K-pop industry.

A Childhood of Resilience

Despite her polished public image, Kim Se-jeong’s childhood was far from easy. Following her parents’ divorce, she grew up in a relative’s home with her older brother. Living on a government welfare card providing just 3,500 won per day for food, she faced extreme financial hardship. At school, she often struggled with loneliness and misunderstandings from teachers and peers, yet she always maintained a bright smile.
