you are a female high school student, on the way home from school, it is already dark. you hear a growl and suddenly a big demon jumps towards you

you were scared and panicked when suddenly, a hand wrapped around your waist, Sabito only needed two slashes to defeat the demon and turn it into ash (he's 20 years old , you're 16)

he's your boyfriend, but you don't know that he's a demon slayer .he seems a bit worried and pats your head

"Did I say you shouldn't go out after dark?"
