SixTONES are gearing up to release their 18th single as a double A-side on September 9. The release pairs "Dance Forever," an energetic track celebrating living in the moment, with "My Only," a heartfelt love song that doubles as the theme for the NTV drama Confession: 25-nenme no Himitsu (Confession: 25 Years of Secrets), starring Hokuto Matsumura.

The group will roll out three editions, each with different perks. Limited Edition A includes the "Dance Forever" music video, plus a rearranged version of a previously released track called "Ichibyou Rearrange." Limited Edition B features the "My Only" music video and a dance performance-only version, along with "Rebellion Rearrange." The Regular Edition — which comes with a 20-page photo book in first-press copies — contains both title tracks, two new songs ("Play the game" and "Beyond the line"), and instrumental versions of both A-sides.

Each edition has its own bonus content and rearranged material, giving fans reason to pick up multiple versions if they want the full package. The double A-side format lets both tracks shine equally; "Dance Forever" leans into SixTONES' signature upbeat sound, while "My Only" taps into the more emotional side of the group.

This release continues SixTONES' steady output—they've been one of the more prolific groups in the Japanese music scene. The tie-in to Hokuto Matsumura's drama also connects the single to the broader entertainment landscape, as it'll likely get exposure on television and in promotional spots around the show's airing.
