To answer you seriously, the situation is basically this.
Ninofags think this means Nino definitely won because they think a garbage bag floating in the wind is evidence that Nino won.
Yotsubafags are pretty much absent in conversation but a lot of people aren't discounting her since there's still an argument that she's been in love with Fuutarou since the start of the story, either because of Yotsurena theory or because of chapter 21. In which case she's still in.
"Itsukifags" because it's hard to gauge who's an Itsukifag and who is anotherfag that's resigned to her victory have taken the stance that reasons to be the kisser can just be applied to her later leading up to the reveal. Your call on whether this is delusional or not.
Otherwise people either accept that 123 are in the bowl and that we're not supposed to know who is yet, or that all five are still in play because of meta narrative purposes. It's generally a shitty topic of discussion, like pretty much everything is these days, because waifufagging means that no one will discuss it seriousy and threads are divided on whether or not context clues are acceptable evidence.
