Mori Ayano, a girl who takes over her mother's debt and spends her days chased by illegal loan. One day, a dubious homeless person introduces her to a super-high-priced part-time job with a detention time of 72 hours and a salary of 300,000 yen. Ayano is suspicious but applies for the part-time job... Did she touch the "place" that should not be touched?

Planned as 6-chapter series.
