This story originated from a dream I had.
In my dream, I realized that I was still studying when I was a child. I was sleeping with my hands on my hands. When I looked up, I found a man looking at me. The sun was shining brightly and his heart was very sweet. Even when I woke up, I felt very happy, so I wrote this story based on the only remaining memory. And this scene in the dream also became the beginning of the story.
