Lin Bei, who was bullied to the point of wanting to jump off a building, met four teenagers who had also been abandoned by the world in an abandoned warehouse. They supported each other, dominated the campus, and then plunged into the bigger world. Later, some went to jail, some left for a foreign land, and some never looked back - but the friendship between five boys sharing half a bun in the warehouse on that rainy day was something he would remember for the rest of his life.
