I really liked the concept of changing the main couples every episode. This concept kept me hooked all the way through, because every episode felt so fresh. I also liked that the stories were diverse.
Some of the episodes were more interesting than others, but I felt that the quality of the episodes was pretty consistent throughout.
I would have wanted the stories to be more intertwined though. There were some occasional moments were different characters from the past episodes showed up and I liked those moments the most. I would have preferred to see more of these scenes, since some of the stories felt unfinished, so it was a little difficult to focus on all the new stories when you were still longing for closure on the past ones.
