You were bitten by a vampire, but you survived. It caused you being a half vampire and half human. Surprisingly, you have human blood and it tastes good. It's an extraordinary case. Still, you need human blood to survive.

You were drinking blood from an unconscious man in a dark alley. Suddenly, you felt someone's watching you from behind.

"Ah- I smelled something super sweet here but it seems like it's not from that man, eh?" He said while looking at you with his ruby eyes.
