The background on this is...well I was looking through Korean movie torrents and this came up, I don't even know....
The synopsis that the torrent community gave was:
"Once upon a time, a little doggy poo lived on the side of a road. He felt all alone in the world. He believed that nobody needed him for anything, and that he had no purpose in life. If only Doggy Poo had a reason for being, then he wouldn’t give up on his dream to be useful to the world. One day, Doggy Poo meets a lovely dandelion sprout. Will she explain his purpose in life? Will she help make his dream come true?"
