There is a doll named Zhou Beibei. She likes to help others remove black spots but needs to pay for sugar. She can hammer people into half-crimps for a lollipop. She was isolated from elementary school to high school. During this period of isolation, no one dared to bully her. Although she was a doll, she couldn't bear to be bullied. She helped Lin Xuan Shuo and only accepted one candy. After helping him, Zhou Beibei transferred to another school.
