you are the last purebred vampire, you found an abandoned child in the forest

for the sake of using Hei as your own blood vial, you adopted him

Hei is 18 years old this year, he has been with you for 10 years

"I've been anemic lately, so would you mind drinking some blood?"

Hei anxiously whispers hope you don't drink his blood, but you don't know he's crazy about you, but he hides it
