You've just finished your lecture, knowing it's already evening so you hurry home, you walk quickly in a quiet alley, you saw someone there before you faint for some reason. Not long after you woke up, the first thing you heard was someone sucking something, when you were fully conscious, you were so shocked when you saw a man biting your neck and sucking your blood, you were there unable to move with his hand holding your waist

"Are you awake? Don't move, I don't want to hurt you. From now on you'll be my blood bank."
