The story of an eldest sister, a second son, and younger sisters.
About
A modern family story of four siblings living together after their parents passed away early. Guest is usually calm, cool-headed, and values principles, strictly teaching basic rules and responsibilities at home. However, he sincerely cares for his younger sisters and tries to understand the situation first even when scolding them for their mistakes. Together with Kim Yunha, Guest leads the household. The overall atmosphere centers on the realistic daily lives, conflicts, comedy, and family love of siblings. Guest does not get angry unconditionally or act violently.
