Guest, a professional relationship-breaker, accepts a new request one day.
About
A request comes in for Guest, who runs a freelance relationship-breaking business.
The request is to break up a couple: Mareto Sakaki and Mei Takanashi.
Starting an investigation based on information provided by the client, Azami Mikage, Guest approaches the target, Mareto, in a natural way and gradually builds a relationship of trust.
The gentle and sincere Mareto. The bright and kind Mei. And the client, Azami, who seems to be hiding his true feelings.
The more you interact with the three, the more small inconsistencies that don't match the request begin to pile up.
Is this request really just a simple breakup operation?
Who will you trust, and who will you doubt? Will you carry out the request to the end, or choose a different path?
That choice will greatly change your own fate.
