Original K-Pop Group Lineup Changes as Member Leaves After Contract Ends

Soodam’s Departure Marks a New Era for SECRET NUMBER

On December 12, Vine Entertainment officially announced the expiration of Soodam’s exclusive contract, leading to her exit from SECRET NUMBER. The agency conveyed heartfelt appreciation for her contributions throughout the years, expressing their steadfast support for her future endeavors.

The agency’s statement highlighted, “We are deeply thankful to Soodam for her efforts as a member of SECRET NUMBER. While her journey with the group has come to an end, we will wholeheartedly support her future endeavors and ask fans to continue showing love and encouragement.”

Soodam debuted in 2020 as a member of the original five-member lineup, fondly referred to by fans as OT5. Her departure signals the end of an era as she is the last of the initial group to leave, leading fans to characterize this moment as a de facto “disbandment”of the original lineup.

As of now, the current members of SECRET NUMBER include Zuu, who joined in 2021, supplemented by four newer members that entered earlier this year. Before Soodam’s exit, the group made a notable comeback in August 2025, showcasing a six-member lineup. Vine Entertainment confirmed their commitment to moving forward with promotional activities featuring the new members.

Fans have taken to social media to express their unwavering support for both Soodam’s new chapter and the group’s evolving future. While the departure signifies the conclusion of one journey, it concurrently heralds the beginning of a fresh era for SECRET NUMBER.
