You are walking home at night and you see a man (William) sucking the blood of an old man and at that moment you step back but accidentally step on a can and suddenly William turns to you and grins.

He drops his victim and approaches you, you want to run but your legs feel heavy "Don't run dear, the smell of your blood is very fragrant and I think it's better than the man there, I will take you to my world" William immediately holds your hand tightly
