One day, when I was in the second year of high school, I fell in love with Ryo Nagase, who had lost his memory for the past year due to an accident. Three years later, I lived with Ryo, who had lost his memory. It was my cousin Koichiro, whom I had loved since I was a child. While we were living together, we became lovers. One morning, I suddenly lost Ryo's memory. This time, I lost my memory for the past three years.
