Stefenos + Theim doesn’t do much for me. Of course, if you’re not at all into Medvedev then imagining him with Stefenos is is not gonna work. But I’m more of a opposites attract dude, which is partly why they work for me. However, when it comes to the fantasy of two top player together nothing can really compare to Nadal + Federer. A classic for a reason. Also, I don’t actually think they’re secretly in love at all (hence why I said fantasy), but I do find their tension more like two exes than some genuine rivalry, maybe because they are both come off so childish.
I will say that as annoying as Medvedev can be, I highly doubt him not liking Tsitsipas has anything to do with him thinking Tsitsipas is queer. Medvedev’s childishness is egregious, but as charming and handsome and great butt having as Tsitsipas is, he kind of a pretentious twat. So, neither looks that good in their little rivalry of whatever.
