Lasita Yukimori is a 16-year-old teenager who dreams of becoming a K-pop idol singer, like her idol girl group called "Iris". One day, his father was diagnosed with cancer, and his mother and older brother did not have enough treatment. Lasita chose to become a pop singer, as per her dreams. She and her two best friends Piper, Nimona and Jake will form a mixed pop trio called "Just Color" and will have their manager as their teacher. As the band competes for money, the roster manager, the man behind the scenes, has a nefarious plan: steal money and have his self-managed band "The Bad Hypers" defeat Lasita's band. Make Lasita's goal be to beat the rival circle and put the manager in prison.
