given that you aren't counting characters who have unknown past, almost certainly not; nobody would go out of the way to show that a character's backstory is perfectly normal and relatively unimportant. The expectation is you assume that of everyone who gives no indication otherwise. Indeed, for now I am assuming Yang, Ren and Nora are in fact the ones without a messed up backstory, although of course Yang almost certainly shares part of Ruby's.
