It was just an ordinary day.... As Rehtona chats with friends in the town square, the world as she knows it begins to change without warning – and another world appears to overlap with reality. Suddenly, Rehtona finds herself alone in the town square – and an unfamiliar door appears before her eyes. A weak voice could be heard behind the door … calling her name. Rehtona musters up the courage to open the door, but she could see nothing but an isolated world beyond it. Then her own world begins to shatter as she falls into unconsciousness. When she awakes, she realizes that she is still in her own world – but that world has now become empty and isolated … similar to what she saw on the other side of the door. She finds a photo lying in front of her house containing a simple yet mysterious message: “Find yourself.”
