I really enjoyed this series... until the last episode.
The series revolves around the relationships of some couples living in a high rise condo, focusing mainly on a single wife per episode.
Most of the episodes offer poignant, if sometime predictable, stories. The biggest problem I had with the individual episodes was that the writers failed to "wrap things up" before moving on to the next one.
Interwoven through all this is the story of Sakura, who is in an abusive marriage and trying to find happiness away from her husband. Unfortunately, the writers lead you on, and then gut punch you in the final episode with one of the worst endings I've ever watched. Disappointing hardly covers it.
It seems to be a trend in recent series that writers want to give you the worst ending possible.
