Fifteen-year-old schoolgirl Sara keeps a major secret: she is "Sala," the new top singer. No one knows whether "Sala" is male or female. She is a devoted fan of the number one group "The Rise," whose lead singer, Hayase Shidou, attends Toua High, a special entertainment school, alongside Sara. Sara discovers that her boyfriend is cheating on her, and to make matters worse, he dumps her! He was only attracted to her because of her resemblance to "Sala." Hayase takes revenge for her in an unusual way, which seems to bring them closer together... but will Sara's mother, who is "Sala"'s producer and co-president of Star Studios, allow it? It is a fact that "Sala"'s true identity cannot be revealed, especially not to the lead singer of her main rival, "The Rise."
