Analysis Of Neil And Riku's Evening Concerts

It was late, yet Neil and Riku decided to sit in on of the last performer of those Evening Concerts of students trying to adjust to the environment and dispose any fear of their audiences. The last performer was a sweet young woman who was obviously uncertain about this environment.
