I watched the new episode, sure things could end up not being Yuri but the show still isn't over yet. I've figured since early on that if it does end up being Yuri she'll need to go through things with Luca/Prince first that then resolve and lead into letting go of that relationship to be with Mari. Maybe it won't happen and the series will end with her being with Luca, however until the series is over we don't know what will happen and the doomposting after every episode lately is so exhausting.
