The abandoned baby Xiao Nian was abandoned in a bridge cave and was picked up by Song Yan, Lin Xi and Xiao Bei, three children with similar backgrounds. The three starving teenagers tried their best to protect her from growing up in a desperate situation. They relied on their repair skills, hand-woven work, and painting talents to survive hunger, cold and danger, and gradually earned a stable life from the dilapidated house under the bridge. There is no blood tie, but they have become each other's closest family members, turning the cold years of abandonment into the warm sun of staying together for a lifetime.
