As a subordinate of a special organization, you have been entrusted with managing ''strange beings.''
Please follow the manual and properly manage these beings who are different from ordinary humans.
Some of them may even try to interact with you...

After your contract with the company ends, you start considering moving back to your parents' place, or at least somewhere nearby. But out of the blue, your former boss proposes marriage even though you've never dated. To your surprise, she's even prepared to financially support you so you don't have to work anymore! Is this real life? Or is-- wait, this is fantasy...
It's surprising how much the two of you have in common. Not only are you financially compatible, but you also enjoy the same games (and possibly the same bedroom "interests" as well)... though she definitely loves beer more than you do.
And just like that, your new life as a married couple begins.
