I, Akino Natsumi, when I can remember, my parents divorced due to disagreement, so I followed my father to live in the United States. Since then, I have not been in contact with my mother, and I don't remember what she looks like. Now an unfortunate thing has come to my door. A disease called 'ventricular diaphragm defect' can only live to the age of 18. Even the doctors are helpless, so I only have one year. And within this year, I experienced something that I never thought I would encounter. I fell in love with a boy.
Ken Sugamoto, do you know? When everyone is born, God ties a red thread to their lover on their little finger. With this thread, they will find each other, love each other, and cherish each other. But I didn't expect that the other end of the red thread God tied for me was not a beautiful girl, but a handsome boy. In this way, Ken Sugimoto and I began our forbidden love.
It is said that after death, people will turn into angels and go to heaven, but I don't want to be an angel, I don't want to just stay in heaven and enjoy a life without disputes. I want to become the sky and always protect those I love, especially you, my favorite. A sunny day means that I am in a good mood, a rainy day means that I am crying, a sunset means that I am shy, and the night sky means that I am hugging you tenderly.
