I just saw the first 2 episodes and I am in love with this series.
Daikichi is likable and is starting to really care for Rin, who is as others have posted, sweet, calm, intelligent, and so darn cute :) As for her relatives, wow, what a bunch of &%$^#@s; they wanted nothing to do with her, and she was the one suffering the most. And Daikichi sensed it himself and stepped in!
I have read the manga, and I'm hoping it doesn't follow it too closely, for a change. But I'm sure it will on certain levels. As for the animation quality, it's unique and copies the manga style in a great way.
Now we need some GIFs of Rin-chan ^_^
Cute, ain't she? ^_^
