Look down on the junior employee and the end result

Look down on the junior employee and the end result. She works in a fairly large company and her subordinate is a guy named Yuki. He made a mistake at work so she and he had to stay at the company to work overtime to fix the consequences. And then that evening, a rain came, making it impossible for both of them to go home. They stayed at the company and the end result for their contempt for the gentle employee was that the female boss was fucked hard.
