シグニチャー / 시그니처
cignature opened with springy, hook-heavy pop and enough stage momentum to carry a small label a long way.

Last updated:
ASSA and ARISONG belong to that first burst; from 2021 the songs soften, and the seven-member shape is how the run is best remembered.
Choose this if you want bouncy girl-group pop that later grew a quieter emotional side.

cignature turn on a move from a bouncy pop line toward something more emotional. The C9 / J9 Entertainment girl group debuted in February 2020 with Nun Nu Nan Na, and the early songs, ASSA and ARISONG among them, jumped brightly with strong hooks and momentum on stage.
The doors are Nun Nu Nan Na, ASSA and Boyfriend. Nun Nu Nan Na and ASSA give the bouncy pop line of the early years, and from 2021 onward Boyfriend and Smooth Sailing widen into a slightly softer, more emotional direction. After members joined and left, it reads most clearly as a journey that ended with seven.
In 2024 Belle stepped away for UNIS activity, and Sweetie but Saltie and Poongdung were released by six members. Activity then ended on November 30, 2024, with disbandment announced on December 3. Nun Nu Nan Na, then ASSA, then Boyfriend covers the bouncy pop, the momentum and the turn toward feeling.
Editors' take Nun Nu Nan Na / ASSA / Boyfriend — a seven-piece out of C9/J9 whose turn from bouncy pop toward feeling fits into three songs.
