This sounds fucking awesome, dear. I'll be reading even if I don't get in.
Part: Old student, or wherever works best.
Appearance: Black hair which is cut very short. (A lot like Audrey Hepburn's) Big brown eyes. Very tan skin because she's Indian. (Indian as in from India, not Native American.) 175 centimeters tall. (or 5'9" if you're using the American measurement system.) Thin, doesn't have many curves, kind of flat chested.
Personality: If you're nice to her, she'll be nice to you. But if you're not, there's hell to pay. Smart, but not a genius or anything. Extremely outspoken and not afraid to stand up for herself.

How your character found out they were gay/bisexual/lesbian: Bi, she just always knew that she liked guys and girls, but didn't tell anyone for a while.
