My Senpai Is Annoying Vol. 1

Futaba Igarashi is a chibi-sized, hardworking OL who is often mistaken for a child. Her job wouldn’t be so bad, though, if it wasn’t for her big, boisterous senpai, Harumi Takeda, who constantly teases and annoys her. She seems to be annoyed by everything he does, from the way he laughs to the way he pats her head and treats her like a kid. But to her friends and coworkers, it’s clear that she actually likes him, she just can’t seem to realize it!
