Jeri Taylor - you may know her as one of the creators of Voyager (before she left the show). So she wrote 2 books for the show. 1 is literally a novel backstory for Janeway. The other is ALL the other backstories for the rest of the crew.
The untold story of Captain Janeway's crew! Pathways is a Pocket VOY novel written by Jeri Taylor. Published by Pocket Books, it was first released in hardback in August 1998.

Again, I swear I am not making this up, but in that book, Harry Kim 100% leads a guy on to believe they
are in a gay relationship before the guy gets his heart broken by Kim's engagement to Libby.
I can't find anything referencing this online (just yet), but trust me, it's there in the book.
