No flaws in acting. One of the pleasant surprises for me us that of Lee Moo-saeng, who played a most unlikeable husband in One Spring Night. Here he portrayed an earnest, sincere, love-sick boyfriend who stuck by his girlfriend even after she was long gone.
This is about the friendship of 3 women, and the soulmate-relationship between 2 of them. It is a journey of the last year of Chan-yeong and how her relationship with Mi-jo and Joo-hul strengthened given the suddenly limited time. While the whole story revolves around the 3, it is also about the different relationships they have outside: with parents, partners, siblings.
My only criticism about this series is that there are way too many relationships under-developed and forced into the picture that they were better off un-introduced, such as Seon-woo's adopted sister, Seon-woo's father.
The romantic angles were also under-developed as the writer seemed to have a difficult time balancing the development of the romantic relationships with the pain of the pending loss of a friend to cancer.
Far from perfect, but still a good watch.
