Busan Beginnings: Kim Min-jeong’s Journey from Military Ambitions to SM Entertainment
Kim Min-jeong was born on January 1, 2001, in the coastal city of Nampo-dong, located within the Jung-gu district of Busan, South Korea. Raised in a household with deep ties to military service—including her father, older brother Kim Jeong-woo, and multiple extended family members—her early environment was defined by discipline, structure, and physical activity. During her upbringing, Min-jeong initially envisioned following her family’s footprint into the armed forces. However, her inherent affinity for performance and creative expression gradually steered her toward the world of music.
Attending Yangsan Samsung Middle School, Min-jeong actively explored various talents. She developed proficiency in musical instruments, including the piano and acoustic guitar, while simultaneously engaging in competitive athletics such as fencing, kendo, bowling, basketball, and badminton. Her passion for movement found a dedicated outlet when she joined her school’s dance team, spending countless hours mastering choreography and rhythm. Despite her growing love for the stage, she kept her artistic ambitions private, never formally sharing her dream of becoming a singer with her parents.
The pivotal turning point in her life arrived in 2016 during a local dance festival at her school. While performing on stage, her raw star quality and sharp dance execution caught the eye of a talent scout from SM Entertainment—one of South Korea’s premier entertainment conglomerates. Unprepared for the sudden turn of events, her parents were astonished when she revealed the scout’s invitation. After passing a demanding audition where she impressed casting directors with her spontaneous vocal improvisation, she officially entered SM Entertainment as a trainee in 2016, setting the stage for a dramatic transformation.

The group introduced a revolutionary ‘metaverse’ concept, featuring digital avatar counterparts known as ‘ae’ that coexisted alongside the real-life members in a fictional digital universe named KWANGYA.

Standing Firm: How Kim Min-jeong and aespa Navigated 2024 Media Storms
While Winter has maintained an exemplary personal track record free of major solo scandals, she experienced the full force of K-pop industry turbulence in early 2024 when her groupmate and close confidante Karina was revealed to be dating actor Lee Jae-wook. The news triggered an intense media storm and vocal backlash from segments of the domestic fan base, culminating in protest trucks stationed outside SM Entertainment headquarters and widespread online debates regarding idol accountability.
When Karina issued a formal handwritten apology to address the fan disruption, international media outlets like the BBC and CNN extensively covered the incident, highlighting the intense cultural pressures and romantic taboos placed upon K-pop performers. Throughout this high-pressure crisis, Winter and her fellow bandmates demonstrated unwavering public and private solidarity.

Kim Min-jeong’s 2024 Pneumothorax Surgery, Recovery, and Triumphant Return to the Stage
Beyond external media scrutiny, Winter faced a severe personal and professional hurdle in April 2024 when she was diagnosed with a spontaneous pneumothorax (collapsed lung). Given the intense vocal demands and rigorous choreography required of a top-tier pop artist, the condition posed a serious threat to her immediate career and physical well-being.
Winter underwent emergency surgery at a major hospital in Seoul to repair the lung tissue. The medical procedure required an immediate pause on her individual activities and a carefully monitored recovery period. Demonstrating remarkable resilience, she adhered to strict medical rehabilitation protocols and returned to full group rehearsals ahead of aespa’s major album rollouts and global tour dates later that year. Her swift recovery and transparent communication regarding health awareness earned widespread respect from fans and industry peers alike.
