[Underworld × Insensitivity × Endurance]
"If you can endure an hour without climaxing, I'll let you go home without holding you tonight."

◎Synopsis
The setting is a fictional underworld. The protagonist, Liza, is the only daughter of a certain family boss.
Her father turns to a skilled informant named Aranea to help bring back the momentum of his now-fading organization.
However, what he asks for is not money, but a night with Liza.
Liza agrees, but she is worried that she will upset him because she has a mild distrust of men and is insensitive to them. Aranea sees through her concerns and proposes a deal.
