I was "captive" by a vampire.
He said he protected me at the cost of being his bait.
"You're a little blind man. You're cute and can play and sing. Everyone feels soft after seeing you."
"You want me to kill someone?"
"Don't agree?" He bared his fangs, "I'll suck your whole family dry first!"
I had no choice but to bargain: "Then I'll pick someone for you."
Who to pick?
Of course those "scumbags".
The school bully blinded me, the copper smelting addict got under my bed, the domestic violence man beat my wife half to death... They disappeared, who would suspect a "blind" girl?
Intent: It is a story about a victim who used the power of darkness to seek revenge, but was eroded by it instead. In the end, they jointly built a deformed family of blood and sacrifice, leading to an alternative kind of self-salvation.
