My Brother Is an All-Round Superstar

She got stuck with a hopelessly unreliable entertainment System, and its first task had nothing to do with the entertainment industry?

That is, until the cast of Yearning for Life ventured into the mountains and discovered the genius little sister she had trained!

Little sister: "The pieces I play are just songs my brother uses to pass the time."

"People use music this difficult to pass the time? How are the piano masters supposed to live? What about ordinary people like us!"
