An unassuming office worker named Kazama Masato just wants to get through his workday and go home in peace. His routine is disrupted when a new hire, Inami Nagisa, joins his team. Nagisa is friendly, competent, and a fast learner, and she also happens to be genuinely cute. But she gets under Masato’s skin with her constant teasing and flirtatious behavior. As the senpai, he tries to maintain his composure, but the more she asks him out or finds excuses to be close, the more his annoyance seems to mask something else. The story unfolds in a typical corporate setting, where Masato’s growing awareness of his own feelings clashes with his desire to keep things professional. The narrative follows the push-and-pull of their office romance, exploring whether what initially felt like an irritation is actually the beginning of a real attraction.
