This summer vacation begins with a car accident…

Our protagonist protects a man from an out of control car, but gets hit and loses his memory in the process. The man he saved happens to be the owner of a jazz bar, sótano. Out of sympathy for his hapless savior, the man decides to set him up with a job and a place to live.

From the outside, sótano looks like a cozy little jazz bar, but behind the scenes they solve problems that the police and legitimate detective agencies won’t touch. The staff there give our protagonist the name “Haru”. He gradually makes his way deeper into the organization, and the hearts and lives of the staff, while working as an apprentice bartender. But just who is Haru really…?

Welcome to our little Agency. I can tell why you’re here. There is someone who is making your life more difficult. It’s no fault of your own. Your every step is hindered by the actions of someone who’s been born onto this Earth just to trip you up. And that’s why you came here.

At our Agency, with just one word and our special volunteer staff will happily lay a complex trap for said individual, the bane of your frustration, and exact sweet revenge on the troublemaker for you, turning their life into exactly the kind of living hell you want. We’ll make them surrender totally to our will, force them into perfect obedience while we punish them for the crime of tormenting you. Of course, we use the word ‘volunteer’ loosely. Payment is always required for our services, but don’t worry – we’ll never ask you for money.

TL;DR: You play as either Kia or Louise, who are paid by individuals to ruin the life of their target in creative ways. Lots and lots of sex.
