Beautiful Musician

My name is Seven, and I'm an up-and-coming musician, a so-called bad boy. I'm also madly, painfully in love with Abby Winston.  Every wild-hearted song I write is for her. Currently she lives in a psychiatric treatment center, and I slip secretly into her room.  Abby is schizophrenic, and I'm a figment of her troubled mind.  She created me when she was a child, and now we're both adults and on the verge of losing each other.  I know I'm not real, but that doesn't change how I feel about her.  Nor does it solve the dilemma of how we're going to survive the ache of not being together for the rest of our lives.
