While these women are the core of the drama, their families and some other characters are also a part of the main cast. The last critical woman is Kim Joo-young, a university coordinator/teacher who manages students’ studies and portfolios to get them into the best universities. All the other families look down on them because of their low roots. Her family is not used to luxury and moving into the posh neighbourhood called Sky Castle is a novelty for them. In contrast to the above women, we have Lee Soo-im, an author from a humble background. She seems to be stoic and a pushover but she is actually quite smart and cares about her children. Jin-hee also dreams of getting her son into Seoul medical university later on.Īlongside them, there is No Seung-hye, the wife of a law professor who is the most elegant of them. She looks up Seo-jin a lot and follows her decisions. Then there is Jin Jin-hee, Seo-jin’s “best friend” and right hand, who is not as polished as Seo-jin but wishes to be. Her family is seemingly perfect on the outside but has several cracks that others don’t see. The most important character is Han Seo-jin, the wife of a high-profile doctor whose goal is to get her elder daughter into Seoul medical university.
While the drama is about four affluent families, the stars of the show are the women of these households and how they run everything. Sky Castle is a dark satirical drama about the lives, motivations, and greed of upper-class families and how it all comes down to academia.
