On the end cliff

Have you ever wondered if the criminal is really a criminal, and the victim is a victim?

After they were good friends and separated, they were brought together by killing game of a psychopath on a train
She was a female, the world killed her, so she became an empty corpse holding on thin thread, which is her feelings towards him
And he was a man with a fragile heart who despaired of the world
They were two bodies with torn souls taking their last breaths
But after death there is rebirth
So will there be a birth for the beginning of love between them?

And most importantly
Will they survive inside that train..?
