Binged this in a span of two days. I didn't have much expectations when I watched it but I ended up thinking that this story was actually done quite decently. While watching, I was wondering what was the writer's purpose for creating a drama involving humans and humanoids. At the end of the final episode, I think viewers will definitely understand why - the message is very simple and serves as a lesson for all humans. The drama had some touching moments that did make me tear up. I found Sun Yao and Yinian's story to be particularly memorable and very touching. The main casts and the various supporting roles really did a great job. However, I still feel that this isn't a perfect drama and the story could definitely have been better developed with more depth for the relationship between humans and humanoids as well as for the relationship development between the two leads Cheng Nuo and An Qiu.
