Haraguro Onzoushi ga Ijiwaru desu

A 28-year-old woman named Shiho works hard to project an image of professional competence at her job. Her colleague, Miyagi, is a good-looking womanizer who often flirts with the women around him, though Shiho is uninterested in him. One day, when Shiho is feeling low, Miyagi unexpectedly comforts her by hugging her. She feels a sudden emotional reaction, but before she can process it, Miyagi's demeanor shifts. He now smiles intensely and declares his intent to make her fall for him.
