A Lord of the Rings Love story: Prologue

Okay! This story is going to be about you! You're an elf named Arianna. You are (at the moment) young for elf years (only 18). You have long black hair and green (very green) eyes. You have a mother, father, and a twin brother (Meldon).
You live in Mirkwood, Middle Earth. Your father and brother are training forThe Last Alliance (NOTE: this starts about 3,000 years before the fellowship of the ring). Your mother is one of the head maids at the Mirkwood Palace. You help her sometimes, although for the past several years it has consisted of you, Meldon, and Legolas, Prince of Mirkwood, going off on little adventures in the palace. Yes, you have lived every elf girls dream: being able to hang out with the prince.
Once the three of you turned 16, the King started having Legolas train as a prince (weaponry, horseback riding, court courtesy), Meldon started training for battle, and you. Well your mom started teaching you the essentials of becoming an elf woman. The three of you hardly ever saw each other.
Every-so-often the three of you find each other and hang out. Now at the age of 18, you have to admit to yourself: you like Legolas as more than just a best friend. You like like him. You make a point to go to the archery range just to hang out with him and kick his butt at archery (you're really good), but you think he still sees you as a young elf girl. Not a young woman.
