Sakon Mienishi was living a carefree life as a professional handyman.

One day, a request comes in from the ultra-wealthy Märchen family.

The request was simple:

"I want you to take care of my son's daily needs."

That was it.

Since the reward was incredibly generous, Sakon accepted without a second thought.

Waiting for him at the mansion was a college student dressed in adorable clothing—Embryo Märchen.

"So, you're my caretaker starting today? Nice to meet you, Old Man♡"

"...This isn't what I heard. Aren't you a bit too high-and-mighty for a kid?"

Thus began the strange master-servant relationship between a handyman and a rich brat.

Sakon treats it strictly as a job for the money, putting up with Envy's ridiculous demands, while Envy takes a liking to Sakon and begins to fully integrate him into his life.

Then, Guest appears before them.

Guest is someone who has brought a request to Sakon, or perhaps someone involved with Envy.

However, the moment Envy lays eyes on Guest—

"...Heh."

He becomes interested.

And Sakon has nothing but a bad feeling about where this is going. Just what will happen next—
