Park So-jin

Park So-jin is a South Korean singer and actress. She leads the girl group Girl's Day as its oldest member and main vocalist. Since debuting in 2010, she has built a reputation for steady vocals and quiet leadership. After the group went on hiatus in 2019, she shifted her focus to acting, signing with Noon Company and appearing in dramas like Shooting Stars (2022). She also writes music and plays guitar, skills that set her apart from many of her peers. Fans know her as thoughtful and grounded, an idol who studied mechanical engineering at university and once taught vocal technique to other artists before her own debut. [edit]

Park So-jin was born Park Young-mi in Daegu, South Korea, and changed her name during elementary school. She grew up in a Protestant household and attended Cheongwoon Church in Seoul. At Yeungnam University, she was one of only eight women among 800 mechanical engineering students. She joined a vocal club there, which sparked her dream of becoming a singer. Before her own debut, she worked as a vocal trainer for the K-pop band Ulala Session. She auditioned for DreamT Entertainment and became the leader of Girl's Day, debuting on July 7, 2010 with the single Tilt My Head. The group struggled at first, facing criticism and a revolving lineup, but Sojin held the team together through those early years. [edit]

Girl's Day broke through in 2013 with Expectation and followed up with hits like Darling (2014), Something (2014), and Ring My Bell (2015). Sojin contributed vocals and co-wrote lyrics for several tracks. She released her first solo OST, Our Love Like This, for the drama Flames of Desire in 2011. After Girl's Day went on hiatus in 2019, she left DreamT Entertainment and signed with Noon Company to pursue acting. She landed a supporting role in the drama Shooting Stars (2022) and has continued to take on acting projects. She also teaches guitar and vocal lessons occasionally, and remains active on social media with her fans. [edit]

Sojin is known as the thoughtful leader of Girl's Day, often described as the group's emotional anchor. Her engineering degree is a point of pride among fans, who see her as intelligent and unconventional for a K-pop idol. She is not flashy on variety shows, but her dry wit and calm presence have earned her a loyal following. Her fandom calls themselves "rubber flowers," a nod to her resilience. In media coverage, she is portrayed as a steady hand who helped Girl's Day survive early lineup changes and grow into a top-tier girl group. [edit]

The collective following for Park So-jin operates under the moniker Daiya, a name shared with her former group Girl's Day rather than a distinct solo brand. While she cultivated a reputation as a thoughtful leader and vocal anchor during her tenure in the industry, the search data does not document specific fan-led campaigns, organized rituals, or viral moments unique to her individual career separate from the group's history. The audience remains loyal but largely defined by their support of the ensemble rather than solo initiatives. Regarding her current standing in the global entertainment landscape, iFANN has evaluated her profile and determined that she does not currently hold a placement in the published rankings (Global Top 1,000 or a Top-100 scope list). This evaluation reflects her enduring recognition as a veteran idol and actress who transitioned successfully after her group's hiatus. The ranking indicates a sustained presence in public consciousness despite a reduced activity level compared to active pop stars. She is not listed on the Global Top 1,000 scale, suggesting her fame is concentrated regionally rather than globally at this moment. Her legacy is anchored in her steady vocals and leadership qualities, which continue to resonate with long-time fans. The evaluation confirms her status as a respected figure in Korean media without attributing her to the recent high-profile marriage narratives surrounding other individuals with the same name. Her influence persists through her musical contributions and acting roles, maintaining a stable footprint in the cultural memory of her primary market.[edit]

Park So-jin once discovered her mobile phone inside a refrigerator, an incident that highlights her occasional absent-mindedness. She enjoys knitting during her leisure time and possesses the ability to play guitar, write music, and produce her own tracks. In elementary school, she changed her name from Park Young-mi to Park So-jin because her parents believed the latter sounded more elegant. As the oldest member of Girl's Day, she holds the distinction of being the only member with a degree in mechanical engineering. A story often retold among her supporters involves her teaching vocal techniques to other artists prior to her own debut, showcasing her dedication to the craft before achieving fame. While some online discussions conflate her identity with an actress of the same name who married Lee Dong-ha, the factual record for the singer focuses on her engineering background and her role as the group's emotional anchor. The fandom, known as rubber flowers, chose a name reflecting her resilience, though no specific solo legends or crowd-fainting incidents are documented for her individual career in the available records. Her dry wit and calm demeanor have earned her a loyal following, distinguishing her from many peers in the K-pop industry.[edit]

Per iFANN's editorial analysis, Park So-jin's net worth stands at $5 Million as of 2026. This valuation reflects her earnings accumulated over years with Girl's Day, encompassing music sales, concert tours, and various endorsement deals. Since 2019, her income streams have expanded to include acting roles in dramas such as Shooting Stars and appearances on variety shows.
