I thought this was gonna be a wholesome story full of happiness but boy was I wrong. This was really good story and perfect at first but I didn’t like them killing of some of the characters that they had no business in killing and especially how the deaths were handled. The second season the story telling had some flaws with the pacing and what that cut out of the story. So here’s some plot holes from the story:
1. what agreement did cass and the empress made in ch 62 that he’ll tell naz after he ascends the throne
2. What happened to angel and prince of valu, like what about his reaction immediately after angel’s death and his funeral
3. How Cass’s mother died, what was his father’s reaction cause last we knew they were still searching for her.
