The hero is what I classify as a "lazy prodigy" super smart to genius level but no ambition, career student, happy with his life, his small social circle, apartment over an arcade and most of all his girlfriend who he has been with since the 11th grade(he is 26) who it took him 4 years to win over. The hero protagonist is one of the only reoccurring male characters in the story, other male characters are either one off villains or obstacles. his Ishmael type companion on his quest is actually female whom I'm writing as a very butch lesbian(based on my real life friend of 10 years) and her girlfriend (based on my friends wife). And the love interest is going to be fully fleshed out from a gazillian angles do to the type of story it is. Cliff notes summery, hero loses the love of his life**(do to death or a breakup, I have not decided yet)** and in grief over the end of the relationship he becomes obsessed with the idea that there is a version of her out there that is still alive or would still love him(depending on whether she is dead or just dumped him), so he creates a way to travel the multiverse and find the right one of her alts in order to get his happy life back. Though I plan on a happy ending, there will be many false starts, some versions are too different, some have way different lives, such as being a single mother or handicapped etc etc.. or sometimes she is basically the same woman and she is into him but the world is too different, such as being post-apocalyptic, dystopian, racist in a Jim-crowe apartheid kinda way.(our hero is multiracial)or it's a world where they are still together and he struggles with the temptation to take HIS alt out and replace him. I showed what i have so far to a few people and though they like short stories they feel the love interest is a problem because there are billions of her, and the hero has an unfair advantage because he knows so much about her going in(friends 4 years a couple for 10), while most of her alts know nothing about him(just met some guy who knows all her favorite things....Wow). Question is would any off you view the love interest/'s as problematic simply based on set-up and if so how would it not be problematic in your eyes?
