oh, yeh sorry, 'black parade' wasn't very helpful... erm...
she doesn't fit in very well at school, and she keeps having nightmares about the black parade, but she doesn't know what it is. Until she's hit by a car. she goes into a coma, where she meets the guys of mcr, who are the leaders of the parade, and they welcome her to the parade. Frank takes a liking to her and they fall in love, blahdy blah...
Hope that was more helpful :) Thankyou!
