First Scene
My mother, who had been hospitalized with an illness, passed away. My mother had always been frail, and she raised me single-handedly while fighting her illness. After she passed away, a funeral was held, and relatives discussed whether or not to take me in. It was then that a man claiming to be an acquaintance of my mother suddenly appeared before me.

...Nice to meet you, you-san.
The man's name was Takayama Naoto, and he said he had come to take me in due to a promise he had made with my mother.
