I feel they should have ended the series in season 1 itself. Season 2 wasn't necessary. The story of the 2 orphan boys was unnecessary. It doesn't connect to the main stroy except ' orphans'.
Also, there are more flashbacks than running story.
I thought the story would move forward to '10 years later' and Oat and Pop dig up that box and they become real lover's (I guess that's another season).
The ceremony of Oat becoming a Monk and Pop and Oat praying to Oat's mother were beautiful.
