What story was that? It was never in any episode of Picard and so far their relationship is lackluster and boring. They don't even make a good, believable or interesting couple. Better to have left seven with her more borglike qualities and alone. She was a way better character in Voyager.
I'm talking about the behind-the-scenes story of how the writers put them together, which was discussed in the Ready Room. Specifically that at a wrap party for S1, Jonathan Del Arco took a photo of the two of them together. They got in close together, and somebody (maybe Del Arco, I can't recall) pronounced them a hot lesbian couple. Ryan and Hurd thought that was an excellent idea, and pitched it to the showrunners.
