Well, I just found this doujin by coincidence, and since it's a Yaoi, I decided to give it a try.
... and I'm not disappointed. The artstyle isn't the best for sure, but still, I kind of liked it. The protagonists don't have a background story (as it's known that's not unusual in this genre haha), and look like young teenagers (14-16). I guess I wouldn't read it a second time though, so it's OK for one go.
Now, at this point I must say that it will only be enjoyable for you if you like Yaoi. So, basically, there isn't really a big story behind it...
