Once upon a time, in a academy for elite students, there lived a girl who was known for her friendliness. She didn't attract a lot of attention but she was friends with many people. Now, in Star Empire, there lived 9 boys who have eyes for her... Adn when she thinks everything's figured out, someone else comes?!
