It's erotic. It's engaging. It's exciting. It's Sundome.
If you've gotten this far, you already know what to expect. Aiba and Kurumi's relationship grow more. We start to infer a little about her past. The art still ranges from average to 'Holy crap, that camel toe looks so painful that I can feel it'.
I like these characters. I like that, unlike so many other manga out there, Aiba actually wants to change. He doesn't like being a loser. He doesn't like being pathetic. And rather than stand around and have great things happen by chance, he works himself to be a better person. His reasoning for being less of a wimp is probably not the best, but he's trying. You can't help but cheer him on.
