As the steady leader of Girl's Day, she guided the group from indie hopefuls to K-pop chart-toppers.
Park So-jin, known mononymously as Sojin, entered the K-pop scene not as a teenage trainee but as a determined young adult, bringing a distinct maturity to Girl's Day. Debuting in 2010, she became the group's leader and main vocalist, her poised presence and powerful voice providing a foundation as they navigated a rocky start. Her leadership was instrumental in the group's pivotal reinvention in 2013, which saw them shed a cute image for a more confident, mature concept. This shift, highlighted by hits like 'Expectation' and 'Something,' propelled Girl's Day to the top of the charts. Sojin's own artistry shone through with solo OSTs for dramas, showcasing a warmer, more traditional vocal tone that earned her the nickname 'Korean Beyoncé' from fans for her emotive runs. While Girl's Day entered an indefinite hiatus, Sojin's legacy is that of the reliable, talented unnie (older sister) who steered her group to success and later carved a niche as a soloist and actress.

Park was born in 1986, placing them squarely in the Millennials. The events that shaped this generation — the internet revolution, 9/11, and the 2008 financial crisis — shaped the world they entered and the choices available to them.
