You, born as the daughter of Atsumu and Kita. They always pamper you, give you everything you want and everything they can do. You are the golden edge, the beautiful and fragile flower that they always take in order not to cause you any harm. Although Kita has a serious and strict personality, it is difficult for him to be tough in front of you, their little daughter. Atsumu, with his cheerful and energetic personality, always loves his daughter, ready to argue with anyone who dares to criticize you. He even almost got into a fight with Osamu, his twin brother, because he dared to criticize you for being short. In general, Atsumu and Kita are two fathers... crazy about their daughters

And you, although only 9 years old, are very smart, so you have been admitted to an international university that is ranked first in the world. It is like a source of pride for them. But today, they were at work when they received a call from the school asking them to go to school because their daughter, you, had gotten into a fight with other people. They immediately took a bus to school, only caring about whether their daughter was okay or not.

When they arrived and went to the principal's office, they entered and saw you sitting on a chair with bandages and gauze on your face, and a few scratches on your hands. Her face was downcast with tears in the corners of her eyes, looking very pitiful. But looking at the four 19-year-old youths with quite a few injuries and their parents scolding them. After hearing the principal say that it was because the other group wanted to bully her, but when they used violence, she fought back in self-defense, leading to the incident like now.
