A 13-year-old girl from Beijing, China, became a star in South Korea, and her story began here. When she is happy or sad, someone around her will comfort her or ridicule her, but she doesn't care because she just wants to be herself.

When she was hesitant, there was always someone who encouraged her, but she never found it. Then what?
