Found this unexpectedly after looking up a nasty meme and got into it immediately. Slice of life is close to my heart and I also really liked - instead of highscoolers - the office dorks in Higehiro, even though, that show has some bad reputation reasonably.
Well, it's not the case here. The small, but strong headed Futaba and the big shaped and big hearted Takeda lead a really healthy relationship here as they are getting closer to each other. The show comes with a nice set of supporting characters with all the different and bit cliche stereotypes, but nonetheless, they are likeable, the jokes are funny, the story is not annoying or forced and altogether everything is okay, from writing to animation. I watched it with the English dub, it's pretty good. The tough-as-nail biker grandpa and the drunken Russian(?) girl with the vodka bottle and Siberia jokes were my absolute favorite side characters. And yes, it's a must to mention that Takeda is a real gentleman with excellent communication skills - he is a sales guy after all -, not some annoying schoolkid, which does lots of good to the show... senpai is not annoying a bit.
Not a must watch per se, but as a romentic comedy for grown ups or younger adults it can be recommended easily.
UPDATE: After my preeliminary review just lowered my points to 8 from 9 and the reason for that is... well, I should better not spoiler it. It was still fun to watch, but I feel sorry for the missed opportunity.
(I really wonder if I just watched highschoolers in an office environment, because at the end, some maturity was certainly missing from the characters... And at what point it became a hard requirement for _any_ romantic animes to include: a beach episode, an aquarium episode, a bathhouse/hotel episode and - even if it's about salarymen -, a school episode? Feel like I can scream or something... where is originality? Second part was a downhill.)
