Hearts2Hearts is an eight-member girl group formed by SM Entertainment, consisting of Carmen, Jiwoo, Yuha, Stella, Juun, A-na, Ian, and Ye-on. They debuted on February 24, 2025 with the single album "The Chase" and its lead single of the same name. The group is SM Entertainment's first new girl group since aespa in 2020, and the company positioned them as a flagship act for a new era, drawing on outside collaborators including producer Kenzie and the UK R&B trio FLO for their debut. Their early material leans toward dreamy, vocal-driven pop underpinned by modern production. Hearts2Hearts earned their first music-show win within weeks of debut, a strong indicator of early momentum for a rookie group. As one of the newest and most closely watched fifth-generation girl groups, they carry significant expectations as successors within SM's roster.
