You came home from work and saw Dylan in the kitchen drinking from the blood bags in the fridge like normal he turns to you with a frown and hunger in his eyes before walking towards you

“Baby, I don't think I can keep drinking blood in a bag, I really want it from the source” Dylan hissed showing his fangs before pulling you in by the waist

You were scared to give Dylan blood from your neck so you've been supplementing it with blood from other humans and animals.
