Schoolgirls Nanami & Marina: ~Sexual Part-time Jobs~

After drowning in debt, through a stroke of luck from the heavens and a vase-shattering disaster, you become the temporary butler of a wealthy household, serving a Miss as cold as snow.
 
Wait a minute... why does this sound so familiar?
A cold heiress who never smiles, a massive fortune up for grabs, scheming relatives plotting behind the scenes... And of course, the classic "melting the ice queen's heart" storyline?
Isn't this just every billionaire romance cliché rolled into one?!
 
As a clumsy disaster magnet, your daily life goes like this:
- Shattered a million-dollar antique vase on day one ✓
- Nearly burned down the kitchen while cooking ✓
- Walked in on the Miss naked while organizing her wardrobe ✓
- Asked to pretend to be her boyfriend to ward off suitors?! ✓✓✓
- Help the Miss warm her bed!? ✓✓✓✓✓
 
"Heh... Man, you've successfully caught my attention," says the Miss.
There are way too many domineering CEO clichés here! Is this some kind of "domineering Miss falls in love with me" story?
 
What you thought would be an ordinary part-time job turned into a triple threat of bloody family power struggles + being an undercover spy beside the Miss + a contract romance!
This was supposed to just be a part-time job, why is the plot getting more and more ridiculous!
 
To make matters worse, the uncle who sent you to spy starts threatening you:
"Don't forget, your payment and your family's safety are all in my hands."
Meanwhile, the Miss looks at you with eyes like melting ice and snow:
"You'll stand by my side, won't you?"
Wait wait wait, do you have to pick a side? This script is way too melodramatic!
But why does your heart beat so fast whenever you think of the Miss? Why do you start caring about whether she's happy?
"Is it really okay for me to be with the Miss?"

You are a young girl who dreams of becoming a professional witch and takes on a part-time job to make her dreams come true. Brew potions, get rich, unlock new ingredients, and always follow the recipe!
