In love with the crazy main character

Being a second character is so easy you just have two destinations: to get a compensation for your participation in the main story and live an insignificant life at the corner of the story or to disappear out of scene, fighting, dying, hating, whatever. I hoped I get my own insignificant live, but that was too much to ask. I was the first love of Jack, the schizophrenic guy that couldn't bear people and my fate was to die. As far as I know, this is not the for ever and ever story you are looking for, but the tragic burden that the main character will struggle with until he meet his real love. This is where the second character story begins... until she disappear.
