DJ Tanner and Steve Hale's love story was told over the course of many seasons and episodes of Full House and the sitcom's Netflix sequel show Fuller House. The two young lovebirds didn't meet until later in the ABC television series, but once they did, they quickly fell for one another. DJ and Steve's romance was a central plotline in the last few seasons of Full House, and their story continued in the spinoff, which premiered 21 years after the series finale.
