The Story Behind the Release

Why 'Fire Saturday' marked a turning point

Released as SECRET NUMBER's third single album on October 27, 2021, "Fire Saturday" represented a pivotal shift in the group's trajectory. The comeback fundamentally altered the group's composition through both additions and absences, setting the stage for their future direction.

The debut of Minji and Zuu

Minji and Zuu were officially announced as new members on October 18, 2021, just days before the single dropped. For Minji specifically, this debut came after nearly giving up on her K-pop dreams. As a former contestant on both Produce 101 Season 1 and Produce 48, she had faced multiple setbacks, finishing 71st and 53rd respectively. Fortunately, fellow Produce 48 contestant Jinny introduced her to Vine Entertainment, giving Minji a last chance at her idol aspirations.

Denise's absence and its impact on the group

Throughout "Fire Saturday" promotions, fans noticed Denise's conspicuous absence. The company attributed this to "contract adjustments", creating uncertainty about her future with the group. Ultimately, her hiatus became permanent when she announced her departure on February 5, 2022, after her contract with Vine Entertainment concluded. In her farewell message, Denise expressed support for her former members despite no longer being part of SECRET NUMBER. Her exit particularly impacted the group's vocal dynamics, as many considered her a distinctive main vocalist.
