Senpai ga Uzai Kouhai no Hanashi

At a certain trading company, saleswoman Futaba Igarashi has managed to hold her respectable job for almost two years thanks to the guidance of her senior coworker—Harumi Takeda. However, due to Igarashi's short stature, Takeda often teases her and treats her like a kid, leaving Igarashi constantly annoyed by his antics. Despite this, Igarashi notices Takeda's reliability as he is always ready to help whenever something at their workplace goes awry. As Igarashi and Takeda spend more time together, their relationship soon develops further than simply being coworkers at the office. Igarashi Futubas new job would be great if her senpai, Takeda Harumi, wasnt so incredibly annoying! Futuba hates his laugh, she hates how big he is, and she really hates that he treats her like a little kid. Just because Futuba is short and looks young doesnt make her a kid, and just because she spends so much time with Takeda doesnt mean she sees him as anything but an annoying senpai...or does she?!
