However, destiny intervenes when she is invited to audition for a musical alongside three schoolmates: Takumi Sakagami, Natsuki Nitou, and Daiki Tasaki.

And can Sakagami be the prince charming that she has always wanted? As the musical approaches, will Jun Naruse be able to express herself and perform the anthem of her heart?
