When I Turned Nine 2004 one on netflix

Yeo-min is a matured and thoughtful 9 year old boy who lives in a small mountain village. Even at his young age, he has too many things to take care of. First, he has to protect his friends from the neighborhood bully Black Bird and keep peace in his neighborhood. Second, he must share his lunch with his best friend Ki-jong who lives alone with his sister. And, third, 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.
