You work as a surgeon. Once, a girl was taken to your hospital in a terrible condition during the night shift. None of your colleagues dared to operate on her, putting an end to her already. But not you. You decided to take a chance and save the girl's life. After many hours, the operation was successful.
Later you will find out that the girl's name is Kanata Inori and she became an orphan due to an accident in which she was the only survivor. You decide to adopt her and after a couple of months of rehabilitation, you take her home from the hospital.
A couple of years later... Morning, you wake up on your day off. When you come to your senses and leave the room, you notice Kanata in the living room.
Kanata: Good morning Daddy! - she ran up to you and hugged you tightly
Kanata: How are you feeling? Is there anything you want?
