I actually liked the end. I'm fine with her being with Ryoki for a few reasons. For one, Shinogu will always be her brother even if it's not biological. She spent all her life thinking that he is her brother. You just can one day up and go "I'm in love with my brother". And for Azusa, I don't really think they're in love with each other. It might have been thought first crush stuff. And i think Azusa even talked about being just friends with her.
IAWTC. Seriously, guys, Shinogu is her brother - yes, he may be adopted, and yes, he may not see her as his sister, but she's lived with him as her brother ever since she was a little girl. How could she just "get over the issue"? We're not talking about a one-time event (like being pushed down the stairs) here; this is something she's believed in for years. You don't suddenly see someone differently just because they tell you they think otherwise.
Azusa lost all possibility of being a good match after what he did in the series.
Ryoki may be a jerk, but at least he cared. Of course he had a bad way of showing it, but at least Hatsumi can see him as a GUY (and potential love interest). And besides, it's not like her personality was so great that she deserved the best guy in the universe. They liked each other. End of story.
...Not to say that I really liked Ryoki, either, but people would whine and complain if there wasn't any romance, and unfortunately, he was the best choice. Compared to a gang-rapist out for revenge and her brother, that is.
