415

415 (사이로) was a dynamic South Korean duo that burst onto the K-pop scene under the banner of High Up Entertainment. Their debut on February 12, 2019, with the single album “그때, 우리 사랑했을 때” (When We Were in Love Back Then) showcased their impressive musical range, delving into genres like ballad, R&B, and urban. Tragically, their partnership with High Up Entertainment concluded in October 2022, leading to their disbandment on November 11, 2022. Despite the end of their journey together, 415 (사이로) left an indelible mark on the K-pop industry with their unique sound and undeniable talent.
