He, the head of the Hyokui Tennis Club and the emperor who leads Hyokui, met her by accident, but this accident took root in his heart and allowed her to enter his own world.
By accident, without her knowledge, he saw her gentleness and carefulness, and the fates of the two began to intersect.
Every time she got close to him, she got to know more about him. She would always unconsciously focus on him, and her heart would continue to fall into his overbearing tenderness.
