This modern series features 3 girl friends aged 39. Their problems are those of grown ups like family and illness. Son Ye Jin looking much like she did in Crash Landing's Seri plays a dermatologist. The second girl friend is about to fall for a younger man. The third is terminally ill. The terminal illness thing was just done in Song Hye Kyo's Now We are Breaking Up. That's not the only similarity. The first episode also features a sexual relationship and then the couple starts the relationship from the beginning. I think this one is better. The dialogue is good and the relationships are mature and supportive. It's only 12 episodes so it shouldn't have become draggy but half way through there is too much about the terminal illness. The pace slows down too much. And they take a long time to say a simple thing. The writer is at fault. Also Yeon Woo Jin as the male lead is a bit bland. There isn't much chemistry compared with Crash Landing.
