This is a story about poison.
Everyone in the world knows that poison causes death, maiming, and madness.

She is a monster, a poisonous thing that is feared all over the world. There are even rumors that her breath can kill people invisible within an inch.
She was his poison and his medicine. She planted the poison in him, so he was the only one in the world who was poisoned by her and still survived.
The blood is their own blood, but what they share is her poison, which lasts for ten years.
Ten years later, life and death are uncertain, or have you not yet thought about it...?
