HP: Miss Snape's Everyday School Life

Octavia had always thought she was just an ordinary little witch, and that her father was merely an ordinary professor at a magic school. But after she enrolled in the same year as the famous Harry Potter, she discovered that her ordinary father could see the future, though his predictions weren't always accurate.

And that famous Harry Potter was strange, too. He seemed awfully curious about her, Octavia, and was always looking at her with a peculiar expression.
