It was a fun, fresh and quick drama that you can watch easily at the end of the day.
For the story, the cases weren't that solid. But as I aforementioned, the episodes were quick and you won't be frustrated. This was not meant to be a long tight story that goes on through the whole episodes and make you think of the world. Some stories weren't that convincing, but c'mon it is just a time-pass drama.
The cast was very good. I can't say it was great, as it needn't master scenes to show their capacities. One of the fun elements; the chemistry among the actors. They were really one team.
I found the music sweet and goes in line with the fast pace of the drama.
One last thing, I can rewatch it easily.
