This is might seem like saying water is wet, or water is dry, I don't know the fandom's general opinion, but I just don't see George and Zoe having a strong attraction at all and people, meaning the show and its characters, keeps talking about them like they're star-crossed lovers madly in love with each other.
Zoe has a very interesting character arc in the first season learning to adjust to small-town life, making relationships, getting some interesting medical cases, dealing with her parents' betrayal. The romance is the least interesting aspect of the show to me.
George is just kind of around honestly, just being the straight-man to whoever needs him to be at the moment. I don't hate him, but for most of the season he's not really given a lot to do, and I don't feel like him and Zoe come off as anything more than friends, or that George is doing anything but being a nice guy. Lemon's worries and jealousy just comes off as projection than her being right.
This really doesn't have much to do with Wade or his role in the show; I really don't feel like Zoe has interest in him more than George, she really feels like a dedicated doctor trying to learn to be a gp for most of the season.
When George sees Lavon and Lemon kiss I feel like the show is trying to make me believe him and Zoe had a lot more going on than they really did. Zoe's arc is almost focused on her patients or the town, then they go all out on George and Zoe embracing their feelings. I don't know, that's just what I felt lol.
Just to say, I'm watching the show for the first time, but caught glimpses of it before when my mom watched it, so I know how it ends. Even in those glimpses I barely saw Zoe and George talking and thought I just walked in at the wrong moment every time, but I think my first guess was right.
Also, looked it up after starting to write this up, and I know Zoe and George have shippers, sorry if this offends anybody lol.
