From Seven Seas:Igarashi Futuba’s new job would be great if her senpai, Takeda Harumi, wasn’t 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 doesn’t make her a kid, and just because she spends so much time with Takeda doesn’t mean she sees him as anything but an annoying senpai or does she? 10c59

Cute and wholesome (full colour!) manga. Quick read.
Really nice /ss/ side couple. Would recommend.
I really like this series as easy reading low-effort fluff. The main two couples are cute and have interesting dynamics. Unfortunately, progress goes at a snail's pace. I am writing this as of chapter 210 and the main girl only just realized she likes Senpai romantically a few chapters back, and I'm still genuinely unsure whether Senpai likes her romantically at all. Even the second couple, which most people consider fast by comparison, only officially got together about 20 chapters ago!
There's also a third couple introduced about 100 chapters in and it's an adult woman macking on a highschool boy about 10 years younger than her. I completely skip those chapters because I just find them gross.
Between these things, I probably wouldn't recommend this series to anyone despite my enjoyment. I would instead recommend something like Nozaki-kun for a series with similar vibes you might enjoy more.

The art and the characters are nice, the pacing is a bit slow, but every chapter is enjoyable, and the story is cute.
I really like it.
I just like to flick through a few chapters for an easy laugh when I have nothing else to read. So far (ch30) there's not enough tension for me to focus on it as the main read
It’s adorable, but it gets old quick with no progression, only diminishing returns.
