Senpai ga Uzai Kouhai no Hanashi

At a certain trading company, Futaba Igarashi has been employed for two years and is fortunate enough to have Harumi Takeda as her senior coworker. Despite being a capable employee, Igarashi is often teased by Takeda due to her short stature and is left feeling frustrated by his behaviour.

However, behind the teasing, Igarashi is able to see Takeda's reliability. He is always willing to lend a hand and their relationship soon deepens beyond a professional one. As they spend more time together, Igarashi soon realises that Takeda is more than just an annoying senpai.
