First off, the acting is flawless! Kim Soo Hyun, Seo Ye Ji and most especially Oh Jung-Se (yes give this man an award!) did a fantastic job on this. Even the supporting casts and minor characters and cameos were awesome too. The casting is definitely on point in this.

The animations also made this show even more vibrant. It was the animation at the very beginning of the show that made me decide I'll stick with this one until the end.

The story is poignantly beautiful. It really was a healing journey indeed. It's slow but sure of what it wants to deliver and portray. It tackled on and made us aware of some mental health issues. The characters all grew on me. I was rooting for all of them. I ugly cried when they cried (KSH and SYJ has a way of making me cry when they start crying). I laughed when they laughed. I was actually glad they didn't go all crazy thriller for the plot twist. It would've not given us the same heartwarming impact if it went on that route.

Overall, it was a great drama that will surely tug the heartstrings of its viewers.
