Review: This drama is one of my favorite kdrama. It has such an interesting plot. The aesthetic and the production was amazing. Everything was done really well ! The acting was especially amazing. Holo was my favorite character, he was so sweet and protective. At the end it was sad to see him “die” but I was surprised when he came back in the last scene.
