One of the few series that has several vantage points,

First few episodes they capture the story of past and future, 4 phones where made that connect each characters on their respective roles, it was refreshing.

after the 2nd to the last time warp, the story did not focus on times, it was back to the same political and scandal story found on other series, the essence of the first half of the series was gone, the bgm and ost are not in sync with the story so the second half of the story is kind of flat.

nevertheless the first half of the story that got me hooked up and it was refreshing.
will i watch it again, I will watch the first half of the series again.
