The story seems to use a documentary/behind-the-scenes filming of three K-Pop acts as a framing device to tell their stories.
One story revolves around Luna’s character, as she gets her start in KPOP in age 9 after being abandoned by her family and taken in by a washed-up KPOP star who controls her whole career (and her), up until she finds love - only to abandon her love to stay a musical star. It’s very “Gypsy”.
Another involves a biracial kid named Brad (Zachary Noah Piser), who was born and raised in the U.S, but is later signed to a boy band in Korea as a replacement for another fired singer. His arc revolves around his struggle between his independent artistry and becoming part of the group identity.
The last plot, which is admittedly thin, involves a girl group who is a backup to Luna’s character and how they all look up to her, but grow weary of not having had a big break despite 10 years of hard work, which causes discord
