How many nine years are there in a person's life?
When she was ten years old, she lost her memory due to an accident.
By the time she was nineteen, she had experienced nine years again.
On that day every year, the same nightmare would always haunt her that night.
Sometimes, she loses herself. Sometimes, she would cling to that memory.
When will her ice-like heart be melted?
"You want a sense of security, I'll give it to you."
"If you want to find memories, I will accompany you."
