tripleS is a 24-member K-pop girl group redefining the genre through an innovative fan-participation system. Through the ‘Gravity’ voting system on their official COSMO app, fans take part in shaping the group’s activities, including the formation of new units, known as Dimensions, and the direction of album projects. This unique structure allows tripleS to continually expand its distinctive musical universe alongside its fans.

Since their debut in 2022, tripleS has established a unique identity through various Dimensions and full-group projects, including ASSEMBLE24 and ASSEMBLE25. Their innovative concepts and global impact have earned them notable accolades, including Best New Female Artist at the 2023 MAMA Awards and the 1theK Global Icon Award at the 2024 Melon Music Awards.

In 2025, tripleS introduced tripleS msnz, a special project combining four units—moon, sun, neptune, and zenith—to explore new creative possibilities. In 2026, the group launched the <LOVE&POP> project, delivering messages of hope and courage to young people navigating an uncertain world. Released in June, pt.1 set the tone for the project, while October’s pt.2, ‘Andless,’ serves as the connective link between pt.1 ‘LOVE’ and pt.3 ‘POP.’

Inspired by the word ‘AND,’ ‘Andless’ symbolizes connection, endless moments, and infinite possibilities. Bringing all 24 members together, the single showcases the group’s dynamic energy and powerful presence, reaffirming tripleS’s distinctive identity and highlighting their limitless potential for future growth.
