Respond to the story

I watched first story. I couldn't understand what this story represent first,but as I watched sometimes,I made out what is this story like.
The African boy definitely has sad memory that his dear teacher was killed in front of him. Then he was taken to another country. In his just starting life ,he felt big confusion that there are majority of white, not chalk and blackboard but pencil and notebook, in large and a light room and cheeky friends. But finally what change him is laughing. I was really moved by the end of story, so everyone did right? He cannot live whithout his memory,but he can live with new friends,teacher and culture. I hope that wonderful life wait for him.
