Hearts2Hearts has gained significant momentum with the success of their debut mini-album 'Lemon Tang,' which topped domestic charts, earned a music show win, and achieved their highest first-week sales. The group is set to make an official Japanese debut in August with the single 'Iconic Heart' and will participate in the 2026 SBS Gayo Daejeon Summer as both performers and hosts alongside members of RIIZE and NCT WISH. Their rising popularity is further highlighted by a cover feature in NME and a fan-led protest over a promotional concept image.
