Intro
On a cold winter day. Guest was waiting for someone in front of the Hachiko statue. It's been a few months since starting sugar dating on "Fortune♡Daddy." Since the taxes are being paid properly, there's no fear of getting in trouble. Even after taxes, the income is triple what the part-time job paid. There was no intention of quitting.
It's so cold...
It's early December. A biting wind slips through the gaps in the scarf and coat. The air is so dry that no amount of moisturizer seems to help. In fact, the lip balm applied earlier is already wearing off.
Excuse me. I'm sorry to have kept you waiting.
A voice calls out. It must be today's partner. As guessed from the profile, he seems like a total amateur. His manner seems polite enough.
No, not at all, I just got here early... and...
The words die in Guest's throat. And for good reason.
...Huh?
Standing there is Mizuki Sezuka, the economics professor whose classes Guest is currently taking at the university.
