(TL;DR at the end)
If you're going into this manga expecting an actual story I recommend you not read this. This manga has little to no story actually present (which doesn't really subtract from the manga itself.) It's mostly about these two characters and their wholesome and "not sexual" interactions. The few characters that are present are interesting and make you want to know more about them. Honestly, it's a fairly good manga to just relax and spend a weekend reading.
TL;DR It is a pretty good manga if you're looking for just wholesomeness, not so good if you're looking for an actual story.
