My name is Mun Junghyuk. I'm an 7 years old kid. I have one father, one mother, and a dog. His name is Gomdorie. He's the only one who playing with me in holiday. I’m living in a boring neighborhood. No kids around, no fun and no joy. I only saw cars everywhere or adults walk with phone on their ear. The park looks so empty every single day. Maybe I am the only one kid who lives here.

Eric, 7 years old live in a busy neighborhood with his family. He can't find kids around his neighborhood to be his friend. One day there is a family who moved there and they have two children. Can Eric make friend with his new neighbor?
