Jiang Ji is twenty-three years old and works as a scrap collector.
Both of his parents are dead, and he lives alone in a tube building to be demolished in the south of the city. His life is as mottled and peeling as the wall covering. No one knew the secret of his body - he used loose clothes and an old belt to tighten and hide everything, including those undue expectations.
He thought that this would be it for the rest of his life, day by day, neither better nor worse.
Until that day, a black car parked downstairs.
The man who got off the car was called Cheng Yan. He was wearing a suit and leather shoes, and he looked out of place on this greasy concrete floor. He held an old photo in his hand. In the photo, a little girl had braids and two front teeth were missing.
Cheng Yan has been looking for this little girl for fifteen years. And what he found was Jiang Ji.
A person who hides too many secrets, and a person who cannot unravel the past.
They all thought this was the end of their search.
No one knows that this is just the beginning.
