I wasn't too sure what I was in for when I started this series and you cannot imagine my delight at realising what an absolute gem this little show is.
The cinematography, editing, pacing, and performances are all stellar and create the perfect atmosphere for the somber but sincere tone the script strikes.
For such a short runtime, the story masterfully addresses topics of burn-out, workplace abuse, and even the meaning of life, in a way.
Its central message revolves around reaching for happiness despite life's apparent pointlessness as well as how relationships connect us as humans and tie us together for better or for worse.
Its critique of exploitative workplace culture (specifically in Japan) is perfect in its simplicity and there are several moments in the show which are so genuinely touching and meaningful I found myself tearing up multiple times.

The one thing I dislike about the show are its brief but inexplicable detours into tired BL cliches which happen repeatedly (although thankfully not all *that* often) over the course of the story. Presumably this is due to the source material, but that still doesn't change how uncomfortable and out of place these moments are.
The main instance of course being the scene in which one character forcibly gives the other a hand-job despite repeatedly being told "no" and "stop". Even putting aside how harmful the "predatory gay man" stereotype is, this scene just feels jarring and superfluous. I understand the intent behind it, but this is certainly the wrong approach.

Despite this flaw I cannot deny how wonderful this show is on the whole and how incredibly touching I find its quiet sincerity.
So if you are looking for short, highly character-driven slice of life drama about two people figuring out what's important in life and finding happiness in one another, then I'd highly recommend giving this a go.
Do beware of the SA trigger warnings though.
