Oof I seriously did not expect this drama to be this great, I'm still high on the feel of this drama. The vibe of this is so dreamy and beautiful and numerous times this stirred emotions in me. It's so gorgeously poignant at times that I felt like I was there with the characters, living in the story. Someone here has aptly described the drama as "dreamy, surreal and almost ethereal".
This drama is really amazing in every aspect. I know some people will be slightly bothered by the AI device but I say, just think of it as a mild sci fi element like you would in a sci-fi movie.
