Episode 8 is something that seems to be interesting but it wasn't that much. As for me, it's not that much a good episode. I really liked previous episodes, but I don't like this episode that much. Mainly because I don't quite understand why and how questions. So, it's just an episode with nothing. As for conclusion, I really hope that the next episodes will be better than this.
