Characters and note

This is after Harry Potter. The world has moved on. His story still a legend that was created into 7 books (or 8 movies :P). But as the world changed, so did Hogwarts. They created a Program called the House Exchange. 4 unlucky students would be announced to switch houses for their entire 4th year. In environments where they don't belong, the 4 students struggle to adapt and fit in. (Note: this idea was formed from a tumblr post I saw. Not my original idea. I was just inspired by it.)
