Each of these episodes is about 30 minutes long. So far with the 4 episodes out currently, the show is somewhat slow paced and attempting to fill the viewer in on each character. The plot concept seems very interesting however it seems like it would get very dragging if it is supposed to be 100 episodes for this series. I think a 16ep would be better for this kind of plot. There are some cliches that pop up but nothing that isn’t expected. This drama shows the complicated relationships between families but with all the characters and side plots that are beginning to form I can see the plot becoming difficult to follow.
