It’s a typical historical romance drama with court politics. In terms of the plot, there is nothing special. I think the later half dragged unnecessarily and especially the last 8 episodes were angsty and draggy at the same time. The ending is indeed confusing - they should have given us a more straightforward happy ending..
Characters:
I loved both male lead and female lead. They are both smart although there are moments where FL did stupid things that are so out of her character. Their CP worked really well.
At first, I had some prejudice against Ju Jingyi because the vibe she gives out and her voice are usually not my cup of tea. But, surprisingly it worked well for this character. Her acting is also good enough.
LFY really loves HYX and protected her since the beginning even when he knew she could be a spy. But, also too protective sometimes. I really want more of the CP working together against their enemies, instead of LFY hiding everything from HYX. Zhang Zhehan really has that domineering charisma as a general or a king.
Gu Qishao is a bit of a grey character. He did use her in the beginning to get the information although he never really hurt her. He redeemed himself in the later episodes when he got freedom to do what he wants to do.
