Jiseok

Jiseok (지석), born Kim Ji-seok (김지석), is the youngest member of Big Ocean and part of one of the most important new stories in K-pop. Under PARASTAR Entertainment, Big Ocean became the first hard-of-hearing idol group to debut in the Korean market, and Jiseok's role inside that story has always been more than symbolic. He performs, dances, records, and communicates with the physical precision of someone who already understands discipline from outside music.

Before debut, Jiseok built that discipline as a competitive swimmer. That athletic background still shows in the way he moves: sharp balance, long lines, and a controlled kind of explosiveness that reads well on stage. Inside Big Ocean, he brings youthful energy without flattening the group into a novelty headline, which is a big reason the team's identity has continued to deepen beyond first-impression coverage.

His page also matters because it shows how quickly his profile is expanding. Alongside Big Ocean releases like Glow, Follow, Underwater, and THE GREATEST BATTLE, Jiseok has also begun building an acting lane through Pado. That multi-track growth gives him a stronger long-term trajectory than a simple maknae label suggests.
