Somehow, this drama just feels so peaceful for some reason. It make you feel happy, sad, angry, curious but at the same time peaceful. It is the type of felling that make you feel like you are being sucked into someone’s memories, as if you were there too. As if you had physically witnessed each scene with your own eyes. In a way, you slowly you realized that you get attached to each characters and too the story itself.

It's not a drama with the loud characters and other kdrama cliches. It's just so beautiful. It's refreshing. This drama is quite therapeutic. A wonderful piece of art. I am not going to comment on the technological aspect of the drama because it doesn't affect me at all while watching, but if I want to be honest, I must admit that I might appreciate seeing more about the creation of the device, but the way it is doesn't hurt at all the story part.

The writer, the production team, the actors really did a great job. The whole team did a great job. You made it possible for me to enjoy such a good pièce!

Overall, I really have appreciate this drama. The mains roles really did a great job expressing the feelings all the way and I simply adored the chemistry between them. I really recommend this drama.
