In the streets and market towns under the bustling city, there are all kinds of people here, most of them are migrant workers who live temporarily. A young man grew up here. He was used to the constant changes in the surrounding environment, but he seemed unable to get used to his perhaps lonely heart. There was one worry that always lingered in his mind. Until they met the boy, they got to know each other through their own surprises. Will the boy in this boy's eyes be related to his future life, or will the things in the boy's heart be answered? Will their encounter finally bring expectations to each other?
Concept: What can stop a person is never the wall in reality, but what really traps a person is always the wall in their own heart.
