Mainly because YEBIN and YOUNG DAE also play in it and are also high school students. In addition, Yebin has a similar behavior in PERFECT FAMILY, where she uses psychological problems related to the family (parental lack) and also uses violence with this need to be loved by all. And I even believe that in the Penthouse, she also has views of the same boy

Many of the main/major characters are similar to the ones in The Penthouse. Even the general plot is similar to Season 1's plot of The Penthouse. For example, a daughter dying and the mother setting out to avenge the ones behind her death and find the killer. The only difference is that Shim Su-Ryeon is more of a morally grey character (and so is Oh Yoon-Hee) and Su-Ryeon is rich and married to a businessman, while Baek Seol-Hee is a poor, hardworking single mother.
