Who are the characters from a step from heaven?

• Young Ju
• Uhmma (Young Ju's mother)
• Apa (Young Ju's father)
• Joon (Young Ju's brother)
• Halmoni (Apa's mother)
• Gomo (Apa's older sister)
• Uncle Tim (Gomo's American husband)
• Amanda (Young Ju's friend)

There might be a couple more characters, but these are what I think the most main characters.
