I really loved mom's character development when she started pushing back against her authoritarian and manipulative husband. Sunshine, Guardian, and House on Wheels 2). Yoon Se Ah was perfect as the meek and kind mom, who unfortunately, was compelled to be competitive by her husband, lawyer Professor Cha (Kim Byung Chul of Descendants of the Sun, Mr. I super loved mom, No Seung Hye (Yoon Se Ah of Snowdrop). It's just unfortunate that she eventually succumbed to the pressure of making sure Ye Seo becomes a third generation doctor in her family. I was proud of her when she fired Coach Kim the first time. It was amazing to see Ye Seo's mom, who's often sure of herself, waver when it comes to her daughter's future. I'm happy to witness another superb performance from Yum Jung Ah - snarky, elegant, and proud when competing with other moms, anxious in making sure she gets the best for her kids and making her mother-in-law (Jung Ae Ri of Tune in for Love, Snowdrop, Crash Landing on You, and Something in the Rain) like her, sneaky and scheming in getting what she wants, warfreak against anyone who messes with her family, and meek yet confident in convincing the admissions coordinator Coach Kim Joo Young (Kim Seo Hyung) to tutor her daughter Ye Seo (Kim Hye Yoon of Cleaning Up, Snowdrop, Record of Youth, Guardian, and My Love from the Star). Mom is Han Seo Jin/Kwak Mi Hyang (Yum Jung Ah of Cleaning Up and Snowdrop). The most prominent among the Sky Castle families is the Kang family. The show takes us through how these families resolve their huge dilemma of making sure that their kids stay on top of the college admissions game versus keeping their morals and integrity intact. The Sky Castle families' lives are turned upside down as secrets about the dirty world of getting kids to good universities are uncovered. Things go crazy however when all of a sudden, Yeong Jae's mom (Kim Jung Nan of Snowdrop, Crash Landing on You, and What Happens to My Family) commits suicide. Like when Park Young Jae (Song Geon Hee of Snowdrop, Love Alarm, and At Eighteen) made it to the Seoul National University (SNU) Medical School. They are always on the lookout for ways to pull up their children's grades and to make sure that they achieve their university goals.

Hence, they are very grade conscious and competitive. Most of the families are obsessed with getting their children to good universities. This drama tells the story of rich families living in a community called Sky Castle.
