Seo Hee Soo used to be a top actress and now she is married to the chaebol group Hyowon’s second son. She puts in all sorts of effort after entering the new world of chaebol families and manages to keep her presence and true colors.
Hyowon’s first daughter-in-law Jung Seo Hyun is a chaebol down to her bones. Born from a traditional and wealthy family, she was born with elegance, dignity, and intelligence. She is also rational to the point that she can maintain a cold expression no matter the situation.
