I'm gonna be real here. If youre someone who watches a lot of cdramas, nothing that happens in this show is going to come as a surprise. The FL refusing to believe the truth about the ML and taking most of the show to truly begin to trust him is annoying yes, but also extremely common. So if you cant look past that then pass on this one. But if, like me, you are easily pleased and not looking for hall of fame worthy shows to pass your time you will probably enjoy this one. Its your typical xanxia, so beautiful costumes, some cool special effects and fighting, and gorgeous actors/actresses. Immortals vs demons so naturally everyone hates everyone. I see a lot of people compare this to Till the End of the Moon and Love Between Fairy and Devil but it honestly reminded me way more of Love You Seven Times with their backstory/past lives.
