Yuu works as a clerk at a small advertising agency. - In this company where only men work, comments that resemble sexual harassment are commonplace. - One day, it was discovered that Yuu had no choice but to go to work without a bra, and people around her started teasing her for not wearing a bra. - ``You don't think it's a good idea to come to the office without a bra, no matter how much you don't want to be treated by anyone, right?'' While they were working overtime alone, the boss was massaging Yuu's shoulders and gradually lowered his hand. - ``If I don't wear a bra, my nipples will rub against each other, won't they?''Then the days of nipple harassment from my boss began.
