Si Yuan, the second daughter of the Si family, was rejected when she asked for piano at the age of seven, was reprimanded for studying opera at the age of nine, and was forced to study painting at the age of twelve. The world only sees her extraordinary talent in writing, but no one knows that she has a whole world of music hidden deep in her heart. The status of a concubine is a prison, but she is not willing to be a caged bird. Late at night when she was eighteen years old, she opened the corner door of the side courtyard and embarked on the road south. From the paintbrush to the sword and gun, from the boudoir to the battlefield, she composed the heart of the piano that had never been heard before into a song of troubled times.
Concept: The piano is talent, the cage is destiny. She cannot break the cage, but she can fly out with her heart.
