It's a new country, a new town, and a new school for Unhei.  So what about a new name?

Having just arrived from Korea with her family, Unhei is anxious about making friends and worried that no one will be able to pronounce her name.  Instead of introducing herself on the first day of school, she decides to pick a new name. The only problem is that she doesn't know what name to choose!
