Shao Daiyu is known as a "delinquent" in her schools. She gets into a couple fights and all of a sudden that's all she does. However, that isn't her at all. Yes, she has gotten into fights but they weren't for no reason. The only reason she hasn't said anything is because people left her alone afterwards. Only when a new student joins her class does she truly change.
