Highschool Phantom Of The Opera

Cristin Daae is alone, and 14. Her father is dead, because of a heart attack.
Now Cristin must move from the French countryside to Paris to be consoled by her closest relatives, Aunt Antoinette Giry and Cousin Meg.
Once her aunt finds out about Cristin's voice, she immediately sends her to the Schola Populaire, a high school that is excelled in the arts.
Cristin befriends the principal's cute son, Raoul De Changey, who coincidentally happened to be a childhood friend.
But one night, Cristin hears the voice of a man, who tells her he is the Angel of Music, and that he was sent to teach her, and to watch over her.
