Kageki Shojo!!

Remembering her past--that of her failed first love (she was technically "friend-zoned" by the one she has a crush with), and after Sawa urged her to "give it her all," Ayako comes out of her being timid and shy to render a stunning performance for the role of "Juliet." It is so incredible that Ai considered her as a worthy rival for the role, and made Onodera-sensei, her most ardent supporter, proud. Ai, Sawa, the Sawada twins, and Kaoru had their audition done, with Sawa, giving her all and making use of some of her ballet skills, doing one convincing portrayal of Tybalt, psyching herself with Sarasa in mind. Meanwhile, while Sarasa gets ready and awaits her turn, she remembers the events before she left for Kouka School, namely when she accepted Akiya as her boyfriend. But when her turn on the audition is at hand, there is a twist: Andou-sensei--"The Phantom"--takes the role of "Romeo." (Source: Wikipedia)
