Well, I guess it is ending, but it had a good run. The author might be tired of it by this point since it's close to 400 chapters now. It was a much better read than Squid Girl, so I'm glad he did it though. Hopefully Daisuke ends up with Gyaru Tanaka (or even non-Gyaru Tanaka) as I feel that she'd be the best choice.
I'd say she's the most attractive to most people (albeit maybe non-Japanese people who seem to like Kotone) and I always felt like she had the most personal chemistry with him, and good chemistry with his family.
