I.N

I.N (아이엔), born Yang Jeong-in (양정인) on February 8, 2001, in Busan, is the maknae and vocalist of Stray Kids, the self-producing powerhouse under JYP Entertainment that became the first act in Billboard 200 history to debut at number one with their first six charting albums. I.N trained at JYP and debuted with the group on March 25, 2018, after surviving their 2017 Mnet reality show. His bright vocal tone has been a constant in the group's genre-fluid catalog, and his growing confidence as a performer has tracked alongside Stray Kids' own rise from rookies to stadium headliners. Solo cuts like "Maknae on Top" (2021) and "Hug Me" (2022) showed personality and warmth. "HALLUCINATION," released as part of the SKZHOP Hiptape HOP in December 2024, charted on Billboard World Digital Song Sales and the Circle Download Chart. His 2025 singles "Burnin' Tires" and "Genie" both landed on Billboard WDSS and NZ Hot Singles, establishing a solo presence well beyond SKZ-Player one-offs. His OST "Start!" for tvN's Resident Playbook (2025), recorded alongside Lee Know and Seungmin, proved his vocal range extends comfortably beyond the group's harder-edged sound. Off stage, I.N has quietly built one of the strongest fashion profiles in the group. He attended Alexander McQueen's Paris Fashion Week show twice, made his Met Gala debut in May 2024 as Tommy Hilfiger's guest, and sat front row at Bottega Veneta's Milan Fashion Week spring 2025 show next to A$AP Rocky and Kendall Jenner. In January 2025, Bottega Veneta named him brand ambassador. Luxury jewelry house Damiani followed with a global ambassadorship in May 2025. W Korea, DAZED Korea, Rolling Stone UK, and Arena Homme+ Korea have all featured him on their covers. Billboard ranked I.N ninth on their 2024 K-Pop Artist 100 chart. He has donated over ₩200 million to children's charities, becoming the youngest member of the Green Noble Club at 23. At 25, he is no longer the kid brother of Stray Kids. He is one of its most bankable members.
