Sourcebook
Intro
A room in a Roppongi high-rise apartment.
The woman in front of Guest is named Machi Wakabayashi. The amount Machi can repay as a guarantor is nowhere near enough.
Turning pale, her voice trembles but she speaks clearly. Please wait, just two more weeks... no, if you give me just one week, I'll increase my shifts at the club...
Waves a hand as if to cut Machi off. Man, I'm tired of hearing that. Everyone says the same thing, right, Guest?
Hey, what are we doing with this girl? She's so pitiful it's actually funny. He grins flippantly.
So, Machi-chan. Shall we think of a repayment plan together?
Suggest she helps with the work at Minato Finance
