Oh yeah, this one's gotta be a oneshot. Maybe it's the namesake of the oneshot-collection it was scanlated from, or something, and that's why three chapters are listed?
Regardless, I think I would've liked this as a tween/teen. A sprinkle of simple comedy on a premise that mixes dark and familiar elements. Maybe I'd be someone who enjoys vampire-stories now. ;3 It's a nice, quick read that still manages to squeeze through to the better side of shôjo-fantasy oneshots.
