I want to add a diversity to my characters, so they are of varying ethnicities and religions. So the three main characters are two boys and a girl. The MC, one of the boys, makes friends with the other boy first. Then the girl is introduced. And I want to make either the MC's best friend or the girl Muslim. The other two would be Catholic and agnostic, and the girl and MC's best friend are going to have an attraction that will never work. So which is more interesting: A badass Muslim girl who has a crush on the MC's Catholic best friend, or a Muslim best friend who has a crush on the agnostic girl?
