My number one pick is firefighters Evan "Buck" Buckley and Edmundo "Eddie" Diaz from 9-1-1. Buck and Eddie have some of the most amazing chemistry and it would be such a waste not to put them together especially with how their connection and bond has continued to grow throughout the series. And neither have had a romantic relationship with even a fraction of the chemistry they have with each other. It would be nice if for once a showrunner recognized the chemistry between two same sex characters that they didn't initially set out to make canon but decided to go with it anyway. And the second half of the sixth season would be the perfect time for them to start to acknowledge their feelings and maybe even go on a date.
