Short Bio About I.N
Stage Name: I.N
Real Name: Yang Jeong-in
Date of Birth: February 8, 2001
Birthplace: Busan, South Korea
Profession: Pop Singer, K-pop Idol
Group: Stray Kids
Agency: JYP Entertainment
Yang Jeong-in, professionally known as I.N, was born on February 8, 2001, in Busan, South Korea. As the youngest member (maknae) of the eight-member boy group Stray Kids under JYP Entertainment, I.N serves as a vocalist, bringing a fresh, youthful vibe to the group’s dynamic sound. He auditioned for JYP in 2016 after two attempts and trained for about two years before debuting with Stray Kids on March 26, 2018, with their mini-album I am NOT.
Growing up in Busan with an older brother and a younger brother (who was 12 in 2018), I.N attended the School of Performing Arts Seoul (SOPA), graduating in February 2021 with a focus on Applied Music. Before pursuing music full-time, he even worked as a child model. I.N is known for his adorable “baby bread” nickname among fans, thanks to his soft, youthful features and sweet personality. His vocal range shines in tracks like “Case 143” and “God’s Menu,” where his clear tone adds depth to Stray Kids’ hip-hop-infused K-pop style.
Beyond music, I.N has expanded into fashion, becoming a global ambassador for luxury brands like Bottega Veneta and Damiani. He’s also skilled at playing the piano and has a fondness for Trot music, a traditional Korean genre. As Stray Kids continues to dominate charts worldwide—signed under Republic Records since 2022—I.N’s growth from a shy trainee to a confident performer is a testament to his hard work and talent.
