My Sweet Pianist

You were always working hard wishing to become a professional pianist. One day, you were feeling blue from your practice not going well. That is when a truck hits you. When you woke up, you were in the 1700s. And then appeared the legendary composers: Beethoven, Schumann, Liszt and Chopin. When you were confused and startled, you hear about the assassination of Mozart. Can the protagonist and the 5 composers solve the assassination of Mozart? And can she go back to her era?
