Surprisingly very well made good quality drama. A short drama that far exceed many so called S+ drama in recent years. A very rare drama that correctly portray how a strong woman should be, as a very composed, smart, brave and calm without loosing her feminine traits and gentleness. (can't stand those dramaa where the woman is stupidly stubborn and domineering). I'm not familiar with the actress, but her performance blew me away, she's able to convincingly portray a character from her bubbly youth, and her development through the years until her late years as a mature seasoned lady.
