Kamatte Shinsotsu-chan ga Maikai Sasottekuru

Corporate drone Masato Kazama just wants to get his work done and go home, but there's a new employee who's making things hard for him. Inami Nagisa is friendly, competent, a fast learner...and even kind of cute. But she annoys the heck out of Masato, especially with all her teasing and flirting. As the senpai, he should be above it all, but her words and actions are especially grating. It can't possibly be that he's into her, though...can it?
