The Royal Waltz TRW

As the only child of a Marquis' house, I have been pampered a bit too much. So much that I am insulted on my first meeting with the first prince of the country.....
I look at the girl in the mirror that faces me. Shiny blue eyes, pearly white teeth and soft golden curls that adorn my..... chubby....face.
'That's it! I've decided. I, Aster Saravelle, am going to diet!'
"Miss, you keep staring at the mirror. Is something wrong? If you're not feeling well, would you like some cake?"
"Cassandra! I am going to diet starting today!"
"But I brought you Osmanthus cake, Miss."
"..."
"..."
" I shall diet from tomorrow! Bring me the cake!"
'And the prince that ridiculed me... just you wait! I will plan revenge..... starting tomorrow!'
