On August 14, Cube Entertainment, announced through an official statement:
We have decided to leave Su-jin Seo from the team as of today.
(G)I-DLE plans to continue their activities as a five-member system, and we will do our best to support (G)I-DLE with our best efforts so that they can show more mature music and performances.
Soojin was accused of school violence in February and was embroiled in controversy. At the time, his agency Cube Entertainment completely denied the allegations of school violence and sued a netizen who posted an exposing article on an online community.
However, her classmate, actress Seo Shin-ae, also confessed to being a victim of school violence. Sujin and her agency decided to leave the group after about six months after not revealing their position for a while.
