Hitorijime Boyfriend was pretty good for being so short. It actually had a couple elements that surprised me, which was good. I figured it would be your typical yaoi story, but, not quite. Probably my biggest issue was that there were a couple random characters thrown in mid-novel and I really have no idea who they were. Some of the lines the characters had were great. Really funny.
The story was nice and progressive. Being only six chapters long, there really wasn't a lot to it. Primarily just the interactions between the main character and the love interest.
Personally, wasn't too fond of it. There's nothing wrong
with it, but, I just didn't like it. Anyway, it was more or less your average art style. The artist seemed to be trying to be more realistic with some characters while sticking to standard art with others.
Definitely the worst. But, again, it's only six chapters long so you can't really spend a ton of time working out every single character's traits. The author did do a good job on the two mains. Those are the only two who really had anything behind them.
I really liked it. It made me laugh and surprised me. It's short so if you've got a couple hours free and like yaoi, why not read it? It won't be a waste of time.
