Yeo-min is a matured and thoughtful 9 year old boy who has too many things to take care of. First, he has to sell ice cream bars after school to save enough money to buy a pair of sunglasses for his mother who injured her eye while working at a factory. Second, he has to protect his friends from the neighborhood bully Black Bird. Third, when a pretty city girl Woo-rim moves into his village, everything falls into a great confusion.
