That seems very nonsensical to me. "Anata wa" is a way of saying "you" the next part, "Watashi wa" means "I" and "hime" means princess, "desu" is teh verb to be so "is:. So, this seems to say "You, I, am Princess Shelby"
I really can't put this one together...it's nonsense, is your friend Japanese....?
Nowhere in there is the word love which can be sukidesu or ai.
