1. After I've finished the series, I really love how Yingyuan doing his responsibilities. I love how realistic some things can be. Love is not everything, even though Yingyuan seems burdened but he still doing his job well as Sovereign Lord while keeping his love. I love how the director make his character a responsible person and not forget his duties even while he fell in love. He really doing his job well.
2. I personally think we should understand the story as a whole because there are some details that are connected either from past or future like the War of Genesis and Celestial-Demon War. It can be confusing at first but it's worth it after we understand.
3. The value of 'Things can't be the same after what happen'. Well it's pretty realistic even in real world. No matter how we try to go back to past times, it's won't be the same.
4. There are some parts that I'm annoyed/can't get over but it's just a small black spot out of this masterpiece. Realistically, every drama has pro and cons itself. This whole drama becomes better as the episodes continue.
Honestly I hope people can watch this with open mind and try to understand from each character perspective.
