What makes this drama so special and unique is the way the sense of loss, the worry of forgetting our loved one and the silent mourning was illustrated. Both actors expressed so many feelings with their facial expressions, especially in scenes like the first kiss. It really caught my breath. The setting and the association with the rain is also super nice. I'm going to watch this drama again because it gave me tremendous comfort with the openness about this heavy subject (loss, fear, death). It was an unique experience.
