When he was five years old, Jiang Yu was sent to the Song family by his father to be a hostage.
Living under someone else's roof for fifteen years, he did the dirtiest and most tiring menial work and endured Song Qi's cold eyes and humiliation. The only light is Song Xiao, the only son of the Song family - the boy who can teach him to write his name with tree branches, secretly bring him hot water, and smile and say "you are my friend".

And the person who pushed him into the chess game was the one who personally sent him to the Song family - his father.
