(( When MP3 ran away from home she worked as a piano player for a cabaret for a little while. While she was there she made friends with one of the singers there and they became very close. He was the only person who actually knew that MP3 was a girl, but because she was going incognito as a boy he jokingly would call her "Mon Ami". And since he sounded like a girl she would jokingly call him "Mademoiselle".
Whoops! I wasn't suppose to write a real description lol 6 u 9))
