Yuu works as a clerk at a small advertising agency.In this company where only men work, remarks simulating sexual harassment were also accepted.One day, Yuu finds out that she went to work without wearing a bra, and she is teased by those around her for wearing no bra. "No matter how much you don't want to be dealt with by everyone, why don't you come to the company without a bra?" While the two of us were working overtime, her boss rubbed Yuu's shoulder and gradually lowered her hand. I'm going to take it down. "Don't you feel like your nipples are rubbing when you wear no bra?" Then the days of nipple harassment by her boss began.
