Completely Alone

Suddenly.
John Doe notices that he's been left completely alone,
everybody has disappeared!
Only a mood of satisfied fulfillment is left.
John Doe decides to hit the road!
He is strolling around in the "New World"
and is totally out of his mind...
The mysteriously.
He is feeling a little bit guilty(?),
like as if he'd let down...
a friend...(?)
