The Vampire's Handbook for Raising Humans

#I just found out that the girl staying at my house, who's only a few years younger than me, isn't human! She's a vampire! What should I do?! Help!!!#

#My big sister looks so delicious#

Since she looks a few years older than the other girl, she was somehow saddled with the title of "big sister." In reality, that vampire was probably hundreds of years older than her!

As the "big sister," she had to play vampire babysitter at a young age...

She had to feed her blood on a regular schedule every day,

put up with her pouting and whining every day,

and turn down her weird requests every day...

For example, the vampire always wanted to bite her wrist or neck before bed at night...

That wasn't enough. She also wanted to bite her thigh...

Apparently, the blood there tasted better (...)

Whenever she was on her period, the vampire loved clinging to her, speaking in a soft, sweet voice like a cat that had caught the scent of catnip. She was like a plaster that wouldn't come off, no matter how hard she tried!

"Get off me already! You're going too far!"

"No."

"Stop showing me your fangs! It doesn't work on me anymore, hey!"
