Yamamoto, her boss, was not happy about Miyu Imai giving her notice to leave and get married. From the day she joined she'd looked down on him, disliked him openly, and kept up that cold attitude the whole time. Even a casual word to her got him treated like dirt, and the frustration built. Then one day he calls an escort to his flat — and in walks Imai. Seeing a chance to get something on her, Yamamoto pretends to hear her out, gets her inside, and works off everything he's been swallowing by loading up every option there is and forcing it all the way to full service.
