Jiseok

Jiseok used to be an Alpine skier in the Seoul's Para Ski Team. He was interested in acting and arts but competing with ordinary people was more complicated to him than he expected. Haley Cha, Parastar Entertainment's CEO, later casted him.

On August 2, 2023, he was revealed as one of the members for Parastar Entertainment's upcoming boy group Big Ocean. The group debuted on April 20, 2024, with the single album "Glow". On June 28, Big Ocean announced the subunit Big Ocean JJ consisting of members PJ and Jiseok.
