Early Life and Education

Seo Soo-jin was born on March 9, 1998, in Hwaseong, Gyeonggi-do, South Korea, specifically in Donghwa-ri, Bongdam-eup. Raised by her father, a police officer, and her mother, a hairstylist, she grew up with a younger sister named Yejin. Her mother encouraged her to pursue jazz dance from a young age, fostering her love for performance.

Soojin also trained in taekwondo, briefly considering it as a career, but her passion for dancing and singing prevailed. She attended Waw Middle School in Hwaseong and later enrolled at the Korean Arts High School, majoring in music, where she honed her vocal skills, jazz dance, and taekwondo.

Her ambition to become a K-pop idol faced resistance from her father, who preferred she pursue a conventional career; it took her two years to gain his approval. Her early exposure to performance arts shaped her disciplined and expressive stage presence.

Career

Soojin’s career began as a trainee under DN Entertainment, where she was slated to debut with the girl group Vividiva under the stage name N.Na (inspired by Vienna, symbolizing music and youth) in 2015. She participated in busking events and photoshoots but left before the group’s debut due to undisclosed reasons.

In 2016, she joined Cube Entertainment as a trainee, appearing as a masked dancer in fellow trainee Soyeon’s music videos “Jelly” and “Idle Song” (2017–2018). On April 10, 2018, she was introduced as the fourth member of (G)I-DLE, debuting on May 2 with the mini-album I Am and lead single “Latata.” As the group’s main dancer, sub-vocalist, and sub-rapper, her charismatic performances, often compared to Marilyn Monroe, earned her a high center position and a reputation for elegant, expressive dancing.

In October 2020, Soojin co-hosted the fashion show Minnie Soojin’s i M THE TREND on Naver Style TV, showcasing styling tips and outfits with bandmate Minnie. Her career took a hit in March 2021 when bullying allegations surfaced from alleged former classmates, leading to a hiatus. Cube Entertainment announced her departure from (G)I-DLE on August 14, 2021, and terminated her contract on March 5, 2022, after police found insufficient evidence to convict the accusers of spreading false information. A school violence committee later cleared her, stating she was a victim of bullying, though the controversy left a lasting impact.

Soojin returned to the public eye in June 2023, opening a personal Instagram account. She signed with BRD Communications in October 2023, debuting as a soloist with the EP Agassy on November 8, 2023, preceded by a dance video, “Black Forest.” Her second EP, Rizz, featuring the title track “Mona Lisa,” was released on May 23, 2024, with another comeback announced for August 2025.

Her solo work has garnered significant streaming success, with Agassy selling 188,026 physical units and her music videos amassing 37.3 million views. She is noted for her smooth, emotional vocals and dynamic dance style, maintaining close friendships with K-pop idols like GFRIEND’s SinB and WJSN’s Eunseo.

Personal Life

Soojin resides in South Korea, likely in Seoul, and remains single. She dated PENTAGON’s Hui in 2018, but Cube Entertainment confirmed their breakup later that year. She has no spouse or children.

Soojin is known for her shy yet caring personality, often called the “mom” of (G)I-DLE for cooking for members and helping with tasks like Yuqi’s makeup. She has eight tattoos, including a heart on her shoulder, “1849” on her hand (a number significant to her and her mother), and “self-love is the best love” on her arm, though her father disapproved of them.

Her hobbies include cooking, fishing, camping, and walking, with a preference for convenience store foods like hamburgers and ramen over snacks. She admires Marilyn Monroe, who influenced her sultry stage persona, and uses an iPhone 15 in pink. The 2021 bullying allegations, though unproven, led to a period of seclusion until her 2023 comeback. She maintains a close bond with her younger sister, Yejin, and enjoys vacations with her friend CherryBerry.
