There are some unnoticed groups of people. Ordinary people may never notice them in their lifetime. These people only spend their daily lives in anxiety, hiding here and there, restless, panicked, and without a nest to live in.
Among the crowd was the girl. Her smile can probably be described as warm and sunny, but she is not a righteous character. Rather than giving this group of people a place to belong to, it is better to say that it is just helping them push them into another situation where they don't know whether it is a blessing or a curse. Rather than being an agency for girls, it would be better to put it bluntly, they are girls selling girls.
Such a girl meets a boy who is not interested in her.
