The story is different from other brother-sister relationship anime. Told from the brother's point of view, it's light and has no weird physical and romantic interaction between the two. I like how he started from not even talking to his sister to how he realizes at the end of the day something new or an improvement with his sister.
Having said that, I like the brother's character a lot. He's sort of ideal as a brother. He acts, responds, reacts and shows his love for his sister naturally as how any boy should. On the other hand, his sister depicts any sibling with a whole lot of pride, asking for help from someone you don't expect to get help from. It's also fun to watch how she turns to her brother for help and learns to appreciate him.
Overall this anime is good and is highly recommended to those who would like to see some family values in a different way.
