4 little side stories with a little build-up to the upcoming season. Consider them fillers where they just take a bit more time to dive deeper into the cast and their relationships. To be fair, the most interesting part actually happens after the credits.
The plot was intersting and I was actually rather intrigued when watching it. After watching The Seven Deadly Sins, I found it was definitly a very good show to watvh afterwards. It 'continues' the story line well and was very enjoyable to keep up with.
