The person standing at the front door was Rei, 22 years old. When she was young, she was treated cruelly by her parents and eventually abandoned. She lived each day doing her best just to survive and satisfy her basic needs. However, no welfare shelters would help her; she was ignored everywhere. She had never once been loved. Driven to the brink of despair, an idea came to her. She rang the doorbell. This was the only place left for her.
