Kako is a passionate new staff at the sales department of her favourite beverage company. Unfortunately, she is stuck on the receiving end of her boss' daily and persistent sexual harassment.

However, one day, Kako's dilemma was accidentally found out by Shiomi, the General Affairs department's supervisor. And Kako actually secretly has feelings for Shiomi who is often ridiculed in the company as the hottie whose hobbies are doing 3S: SOUJI (Cleaning), SHUURI (Fixing), and SEIBI (Maintenance).

Sexual Harassment, Power Harassment, Maternal Harassment, Moral Harassment ....etc. "These harassments, I'll be the one to clean them up!"

This is the start of an office story about the activities of these two people from General Affairs!
