First of all, if you're looking for a read that's similar to Tomo-chan wa Onnanoko, then you're looking in the wrong place. This manga is not even remotely similar to that manga despite being written and drawn by the same mangaka (although the art style is similar, but that's it)
Despite this, I wouldn't call this manga bad by any means, the story is humorous and odd with a very unique dry sense of humor that is refreshing despite it's very odd basis that lacks impact if spoiled. It's a short and sweet read that highlights the relationship of a young adult male and a barefooted girl that he finds outside a convenience store.
The art is the same as the vastly more popular Tomo-chan wa Onnanoko and you can see the fact that the same mangaka wrote and drew both works, a very simple design that delivers all the impact that it needs to without being bogged down by hefty detail in a very charming fashion.
The characters are the main point in this manga and it certainly shows, despite the length of the doujin the characters don't feel skimped for detail, they are both interesting characters that interact in ways that seem extremely odd in an endearing, lewd fashion that at times seems as awkward as you might think. But that's really the charm and point of this manga and it achieves it superbly.
To summaries, this is a short, semi-lewd, awkward, oddball doujin that has a very distinct style and theme that although weird and not for the sensitive can be enjoyed by those who look past it.
