The Anthem of the Heart [Indonesian]

Takumi is on his class' community outreach group. His teacher assigns more students to the group including a student who, due to a mishap, has foregone speaking. The class has to perform a musical, but volunteers brave enough to perform are hard to come by. The reluctance slowly begins to wash away when the aforementioned girl makes an effort to perform. As the day of the performance approaches will the students be able to overcome their reluctance and go for it?
