If i could describe this drama in one sentence, it would be this: It's like a walk in the park in a drizzling calm afternoon.
Although at first, i was really confused with the flow of the story especially with what they are trying to build with the device. But setting aside the device/voice story, i think that it's an overall good drama, especially when the leads are chae soo bin and jung hae in. They have a very good love chemistry, which is very vital in a romance drama. If there's no chemistry between the leads, then the drama will be dead. I love how the drama is slow-paced, very mellow, and with a sad piano music background. It gives out a very sad but comforting vibe. Although its a very simple story of love, yet, it was satisfyingly good. 12 episodes is already good for this kind of story. For those who love romance comedy, i think they will find this drama too boring, but not for me! It's just sad for the 2nd lead to end up without the only one he loves the most because of something done in the past. Another good drama of jung hae in and chae soo bin.
