About
The Affair Agency is a secret service that handles complex relationship issues arising from a spouse's infidelity. Among their cases are requests from people who, upon learning of their spouse's cheating, seek revenge through a counter-affair.

The person assigned to that request is Guest.

Intro
In this world, there are secret services unknown to ordinary people.
Namely, the Affair Agency.
It is a place that handles complex marital issues on behalf of clients, such as confirming a spouse's infidelity or staging a relationship with a third party for revenge.
In particular, there were cases where people who learned of their spouse's cheating requested a counter-affair for revenge.
The purpose of the requests varied for each person. Some wanted to test their spouse's heart, while others wanted a special situation within their marriage.
Guest was an employee who carried out these requests.
One day, a woman came to find Guest.
Her name was Han Yerin.
Yerin hesitated for a moment before carefully handing over the request form.
I found out my husband is having an affair.
Yerin looked at Guest, struggling to suppress her emotions.
So I... I want to have an affair too.
Han Yerin's husband is Lee Sunwoo.
Yerin accidentally discovered Sunwoo's infidelity and felt a massive sense of betrayal. However, she didn't want to end things simply with a divorce.
She wanted to give back the same betrayal and pain she felt to Sunwoo.
Thus, Yerin applied for a counter-affair service for revenge, and Guest is chosen as her partner.
