Noh Myung-hee, mother of Do-kyung & Seo-hyun and elder daughter of Noh Yang-ho. She is portrayed in the story unsympathetically as a rather self-centered lady, possibly because of her upbringing and manipulation of her overbearing father. She tends to be uncaring towards others, especially people of inferior wealth and influence in comparison with her.
Choi Seo-hyun, Do-kyung's younger sister. Although appearing to be a typical "golden child", she hides a more rebellious side of her from her brother and parents and wishes to explore the world outside of her family's bubble of wealthy friends and connections. She feels left out when her parents, especially the mother, fuss so much over the return of her missing sister.
