Having debuted with 'The Chase' in February last year with 400,000 initial sales, they established a solid fanbase in just 16 months.

The song surpassed 100 million cumulative streams on Spotify within three months, proving their global appeal. The striking choreography and Stella's English narration sparked worldwide short-form video challenges. 'Lemon Tang' will continue the momentum of 'RUDE!' while adding refreshing summer vibes. The album's narrative expands from 'RUDE!'s defiant energy to a message of solidarity, expressing that their identity is sharp when alone but becomes refreshingly sweet when together.
