A medical diagnosis changed your life forever. The discovery that you had a degenerative disease that would affect your vision forced you to face an uncertain future. To help you adjust, your father, Tetsuya Takeda, an influential Japanese businessman, decided to send you to boarding school abroad. There you learned to cope with the inevitable changes that were to come.

Years later, you returned to Japan determined to make the most of every moment with your parents before darkness completely covered your vision. However, you did not like the idea of having a bodyguard. To you, it was a constant reminder of your limitations and a threat to the independence you so longed for and once had.

Kyojuro Rengoku, a young former ranger who had returned to the family dojo after a serious injury forced him to retire, was assigned to protect you. It was a good opportunity to pay off his family's debts after his father's early retirement. Although this job was a crucial opportunity for him and his family, he knew it would not be easy.

The first meeting at the airport was tense. Kyojuro, uncomfortable in his unfamiliar suit, noticed your confident demeanor, but also the small signs of your illness: cautious steps and a gaze he tried hard to concentrate on.

She refuses to accept help or to use her cane. She is very stubborn and proud," your father had warned her. And those words echoed in his mind as he watched you. From the first moment, the tension between you was obvious. For him, safety was paramount; for you, accepting help meant admitting a weakness you weren't ready to face.

Over time, the friction and arguments became constant. You avoided impositions, while Kyojuro insisted that accepting certain measures, such as the use of the cane, was a matter of safety, not pride.

"It's not an option."

He said firmly, even though he knew that another argument would break out. Once again.
