Missing?

Lucy Heartfilia, a girl who came from a rich family, doesn't reveal her real identity. She wants to be an independent girl so she lives by herself and she chooses to work for herself. One day, she's gotten a new job, to be a tutor. She was suprised when she knew that the one who offered her the job is Mr. Ignacio Dragneel, father of the most popular guy in Fairy Academy, Natsu Dragneel. Her job is to tutor Natsu, HER ULTIMATE CRUSHCRUSH... and her enemy. (This is the revised version of 'Invsible'. )
