Jung Woo-seok, known mononymously as Wooseok, is a South Korean rapper, singer, songwriter, and composer. He is the main rapper and youngest member of the boy group Pentagon, which debuted in 2016. Beyond group work, Wooseok formed the duo Wooseok X Kuanlin with Lai Kuan-lin in 2019 and launched his own rock project band KIK in 2025. Known for his deep voice and towering height of 191 cm, he has also stepped into acting, signing with S27M Entertainment in 2025. His music blends K-pop with rock influences, and he is deeply committed to creating a shared energy with his fans. [edit]

Wooseok was born and raised in Gwangju, in the Buk-gu district of Yangsan-dong. He grew up with his older sister Sojin. From a young age, he studied violin and piano, winning a Special Prize at a violin competition. He attended Yangji Elementary School and Jisan Middle School in Gwangju before moving to Seoul to attend the School of Performing Arts Seoul, where he studied Stage Art and graduated in 2017.

His dream of becoming a K-pop idol led him to audition for Cube Entertainment. During his audition, his bright personality caught the attention of female viewers. He trained for several years and participated in the Mnet survival show Pentagon Maker, which determined the lineup for Pentagon. He successfully secured his place and debuted with the group on October 10, 2016. [edit]

Wooseok debuted as a member of Pentagon on October 10, 2016, with the mini-album PENTAGON. He quickly became known as the group's main rapper and sub-vocalist, contributing to songwriting on many tracks. In March 2019, he formed the duo Wooseok X Kuanlin with Lai Kuan-lin, releasing the EP 9801 led by the single I'm a Star.

After leaving Cube Entertainment in October 2023 alongside four other members, Pentagon remained active. Wooseok signed with UNDFND Entertainment in January 2024 and made his solo debut with the single Empty Paper. In 2025, he created the project band KIK, serving as frontman and leader, and released the rock-influenced EP ender to ander. He also signed with S27M Entertainment for acting. In April 2026, he released the album An attic. [edit]

Wooseok is known for his deep voice and commanding rap delivery as Pentagon's main rapper. His tall stature and youthful visuals contrast with his low vocal tone, creating a distinctive stage presence. With the formation of KIK, he has embraced a rock aesthetic, citing influences like Red Hot Chili Peppers and Oasis. He has expressed a desire to foster a team-like bond with his fans rather than a traditional artist-fan hierarchy, saying he wants them to share the same space and energy. [edit]

Wooseok has cultivated a deeply loyal following that spans the journey from his days as Pentagon's towering youngest member to his current chapter as an indie rock pioneer and actor. Fans, who primarily identify as Peniel under the group's collective banner, have followed every pivot in his career with intense devotion. The narrative of his 2023 departure from Cube Entertainment became a defining moment for the community, celebrated not as a loss but as a brave step toward artistic independence. Supporters rallied behind his transition into the rock genre with KIK and his solo projects, viewing his reinvention as a reflection of resilience. His direct engagement through social media bucket lists and fan meetings in Japan has strengthened this bond, creating a space where fans feel like equal partners in his creative evolution rather than distant observers. This shared energy is central to how he defines his relationship with his audience, fostering a team-like dynamic that transcends traditional idol hierarchies.

While Wooseok remains a beloved figure within the K-pop sphere and the broader indie music scene, iFANN's Global Fame Engine has evaluated this person, but they do not currently hold a placement in the published rankings (Global Top 1,000 or a Top-100 scope list).

Jung Woo-seok carries a cow face emoji as his representative symbol, a quirky detail that fits his warm personality. He harbors a fondness for anime, spicy cuisine, and competitive StarCraft matches, while dark tones remain his preferred color palette. A peculiar aversion to cucumbers stands out among his dislikes, and he possesses the surprising ability to sing soprano parts from operas. His role models are the senior members at Cube Entertainment, and his musical DNA draws heavily from Red Hot Chili Peppers, Oasis, and Foo Fighters. Physically, he boasts a foot size of 280mm and a hand length of 21.4cm, traits that contribute to his imposing yet youthful stage presence. His MBTI type shifted from ENFP-T to INFP over the years, reflecting a maturing introspection.

One enduring legend surrounding him is the "Giant Maknae" persona, a story fans still retell about the contrast between being the youngest member and standing a towering 191 cm tall. Another pivotal chapter in his lore involves the October 2023 split from Cube Entertainment, which marked a major turning point where the original lineup fractured to pursue new artistic directions. His successful pivot to independent rock artistry with the EP ender to ander has become a celebrated narrative of integrity, proving his ability to redefine himself outside the mainstream idol system.[edit]
