My Senpai is Annoying

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?!
