Soojin

Seo Soojin was born on March 26, 1998, in South Korea. She joined Cube Entertainment as a trainee and was selected as a founding member of (G)I-DLE, officially debuting with the group on May 2, 2018. Known for her exceptional dance technique and striking visual presence, Soojin was widely recognized during her tenure as one of K-pop's most technically accomplished performers in her generation, contributing a powerful, precise dance energy to (G)I-DLE's early performances.

During her time with (G)I-DLE, Soojin was frequently highlighted for her commanding stage presence and clean execution of the group's complex choreographies. Her aesthetic and physicality were central to the visual identity of the group's early era, and she contributed meaningfully to establishing the performance standard that (G)I-DLE would be known for. She is particularly associated with the group's debut and pre-2021 titles, for which her performances are still frequently referenced by longtime fans.

In August 2021, Soojin departed from (G)I-DLE and Cube Entertainment. Her absence marked a significant transition for the group and their fanbase, as the remaining five members chose to continue as (G)I-DLE and proceeded to release some of their most commercially and critically successful material in the following years.

Soojin's contributions to (G)I-DLE's early history remain part of the group's complete story, and the performances and recordings she participated in are part of the group's official discography. Her technical skill and visual impact during her tenure are acknowledged by fans as a meaningful part of (G)I-DLE's foundation.
