Just starting, but already seems fresh and very watchable

Started watching out of curiosity and was pleasantly surprised at both the quality of the storyline and character development. The story seems a fresh take on some common elements, (aging, health and gender and family dynamics). And even watching only two episodes, the characters seem well-rounded and relatable with great potential for further exposition. Think "The Good Wife" (another pleasant surprise), with the same quality of acting and writing, only with additional story elements and in a Korean Hospital instead of a law firm.
