I've done watching the episode 18. I'm not used to this, sharing my feedback about the series. :>
As the story goes, it becomes more and more interesting. But, I was disappointed with the ending. I expected more from the ending. The last 2 mins from the series made me confused. Is it intended to end the part 1 or there would be another season? (something like that.) There were many questions that needed to be answered. I hope there would be another season with the same cast (I hope.)
