There is a running joke among my friends, you put a "warning: adult content" image in a post and then talk about your work, children, spouse, health or about the lack of any of those things. The joke being that most actual adult themes are not that thrilling, just the kinds of things that happen in a normal life after the adventures of the 20's pass.
This manga is an adult manga.
The story can be read either as a work-related or as romance, but either way, it's an adult story, its worries are not easy to understand for someone young and the plot is not of the mind-blowing sort. Someone is looking for a job and gets a job, someone is trying to find love and love finds them. All very normal and extremely exciting for someone that never sees that kind of story in the wild (most josei and seinen manga that I have access to are either about children and teens or set in fantastic, science fictional places. Even the adult romances are usually unrealistic).

Other than the blatant realism, what actually makes the series are the characters: all multifaceted people with opinions, lives and interests. Their conversations, their relationships and the way their lives intertwine are extremely compelling.

I also enjoyed the art, because its simplicity serves the story so well, without overshadowing or short-selling anything. I specially like how each character has a wardrobe (not the same clothes all the time, but a handful of clothes that they switch around) and how people look different when they've just woken up.
Those little details, coupled with an extremely tight narrative and paneling* made me actually miss this manga after I finished it. It's like missing talking to your last job's coworkers, a strange kind of nostalgy.

So I really recommend this story. That is, if you're an adult and interested in other people.


* I actually feel nostalgic for good storytelling in manga because so many mangaka take 160 pages in a single fight scene, date or impact event.
