Think of 18th century. It's 1862, in London. Your walking the streets, your hand is locked with a boy about your age, 17. The boy suddenly leans to kiss you and you do the same. Then you both get shot in the arm. The last thing both of you see is each others eyes. You both collapse to the ground and a doctor comes over to you both. He turns you into vampires. Your family, who walked nearby collapsed crying, when you awoke, you and he were vampires.
