My Senpai is Annoying

Futaba Igarashi wants to be treated as a capable adult at work, but her senior colleague Harumi Takeda has a habit of treating her like a child. His loud personality and constant involvement in her day make him a frequent source of irritation.

Workplace mishaps and encounters outside the office keep bringing the two together. As Futaba spends more time with Harumi, her frustration becomes mixed with a growing closeness she is reluctant to acknowledge. Their everyday routine turns into a workplace relationship where annoyance, familiarity, and possible affection are increasingly difficult for Futaba to separate.
