Synopsis:
The protagonist is a salaryman who is not good at his job.
A woman who was his colleague has become his boss before he knows it and a woman who was his junior has been promoted to a higher position.
At the company he is looked down upon by those around him, treated like garbage, relegated to the warehouse, and is on the verge of being laid off.
While cleaning up the warehouse, he accidentally finds an app installed on his smartphone.
The protagonist, who was skeptical, tries the app on a random woman at a brothel...and to his surprise, it's true!?

In order to release the humiliation and resentment he has endured up until now, a revenge drama against the women at the company begins (͠≖ ͜ʖ͠≖)
