Four actors - female lead, male lead, former boyfriend, and his assistant are all worth watching. Their acting is solid and sincere. I found the rest of the actors largely overdone, especially the female lead's mother -- an obnoxious motormouth. She was bad enough that I turned off the sound and just read the subtitles when she came into a scene. I am going to be magnanimous and assume that most of the supporting actors were told to act like dull-witted stereotypes and that they did their best to fulfill those instructions.

The story line was above average for the first 10-15 episodes, then it lost focus until the last two episodes. Rather than being outright bad during the middle episodes, situations and dialog became somewhat predictable and repetitious. There were some very good moments that included realistic friends for each main actor, with honest, believable dialogue, and several conversations that keep it from failing the Bechdel test. Definitely overkill on the flashbacks, though. I would rewatch this with a friend, rather than rewatching it alone.
