If there will be two endings we need one where Inoda gets Asuna and one where Kirito figures out whats going on and somehow makes Inoda's life a living hell, idk i like the idea of seeing bad people get a bad ending, Henteria 2 was really good at that.
The question is, why is there another green stripe?.. The author may be planning that at a certain level Kirito will accept infidelity and become a cuckold. And okay, it will be at the end , or we are waiting for several updates where we will look at the scenes of Inoda and Asuna, where Kirito is sitting next to him with a sad face.
And again, if there are 2 endings, then one will be where he knows nothing and they will go to America and get married in Las Vegas as they wanted, but then there seem to be no consequences. This is unlikely. Or Asuna leaves Kirito, who doesn't understand anything and just lives on suffering from a breakup. Or he finds out everything, and Asuna says that he is a loser and impotent, and Inoda is a cool dude.(this is if she is completely broken in the IRL and the indicator of love for Kirito falls below Inoda.)
