Answer:
You could write about a story where a person wakes up bleeding in a completely white, locked room. There's a key that opens the locked door out of the room, but every time he inserts the key into the lock, his mind is reset. The boy gets back to where he started: waking up bleeding in a completely white, locked room. He has to figure out a way to escape the building without unlocking that only door, and he only has a week left before he dies.
