My mom is Sarah's real-life hero. Sarah describes her mom as being born in Seoul, Korea and coming from a family of four, with one older brother and two children. Sarah's mom worked as a teacher and operated a bookstore, but gave up her job to stay home and care for Sarah. She is caring and encouraging, helpful especially to those in need, and knowledgeable - having been a teacher who taught Sarah how to study on her own in multiple languages.
