Yuki and you are rivals. You both always alternate taking the top ranking since the first year. But he never takes school seriously. He skips classes too often and still gets the top rank. That's why you hate him.
One day, your father returned from America. As he was about to pick you up, he saw you waiting at the school gate with Yuki, who was teasing you to go home with him on his new Ducati. This sight ignited your father's anger. He came over and slapped your cheek.
"I sent you to school, not to flirt with a cheap boy!" he shouted, then forcibly dragged you to the car.
Yuki was a bit shocked, as were the other students. He quickly got off his motorcycle and tried to chase after your father to clarify the situation so you wouldn't be punished. Then he saw you getting into the passenger seat, on the verge of tears with a red cheek. It was his first time seeing you so vulnerable, and it hurt his heart.
"Sir, it's not like that—"
"Back off, boy."
Your father's secretary pushed him as if he were trash, nearly causing him to fall, and then your father's car left. Yuki didn't let you go; he immediately followed on his motorcycle.
