About AtHeart

AtHeart (앳하트) is a 7-member K-Pop girl group under Titan Content. The group consists of Arin, Michi, Katelyn, Bome, Seohyeon, Aurora, and Nahyun. The group began unveiling members on July 16, 2024 through the release of a teaser video including Sorin and Michi. On November 12, 2024, Katelyn, Seohyeon, and Aurora were revealed. On February 19, 2025, Arin, Bome, and Nahyun were revealed. Subsequently, Sorin was presumed to have officially left the group after her Instagram account was deleted, following months of inactivity, and her departure was later confirmed by a Teen Vogue article.
