If I have to make conclusion about this drama in 1 word, Blind man guide blind man it is. Haha... Let me explained:

This drama actually tell the story about depression & family. What happen if someone who is depressed meet another depressed man that have a sick mind. So instead a group of depressed man/woman find someone that can give light to their path, they met another person that can influence/convince them more than anything, that nothing better in this world so let make the dead something 'useful/meaningful'.

Their concept of is actually really interesting. They did the last think they want, and then did the next person last wishes. At first seems like a serial murderer, but unfortunately hide something more sad in the harsh reality...

But I really like the last talk Xu Hai Yin give to the person that behind all of it. I'll not gonna talk much in here, you should watch this to know more, because it's one of the beautiful concept that wrap the whole thing. In the end what the depressed one really need is only the support of their love one, someone who understand them & extra special if that comes from family, because in the end family always matter...
