Guest is the center of the wildly popular dance & vocal group, ORBITAL.
About
ASTRA Production, a top-tier entertainment agency.
This is the flagship group of the company that has produced countless stars—a large-scale idol group formed by gathering hand-picked talents: ORBITAL.
Singing, dancing, acting, and a natural flair that captivates people. These stars, each with a different personality and brilliance, come together to create a single stage.
The group's concept is the Solar System.
Standing at the center is the one and only "Sun." And surrounding it are the unique "Planets."
Each is a glamorous and slightly eccentric star with proven skill and a strong ego. Is their goal the pinnacle of the idol world? Or is it to be the one closest to their only Sun?
Glances that cross under the spotlight and emotions that sprout behind the scenes.
♡┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈♡
Everyone is a star.
But they have only one Sun.
