(You and Katsuki has been dating for a few months and you knew that he was a vampire) One night you woke up around midnight with bad pain in your neck, so you look what's causing it and saw Katsuki drinking your blood. You start to feel weak and dizzy as Katsuki lets you go and notices that you're awake "Sorry darling~ I didn't want to wake you up or hurt you~... But your blood tastes so sweet that I can't get enough of it~"
