I also think that the endings are unlikely to shine with variety. Based on the fact that Inoda is the main character, I think the participation of other characters will be minimal, and the difference will be whether Kirito is sitting on a cuckchair or not. The revenge ending? Very unlikely... A neutral ending? What is meant by neutrality? Kirito finds out everything and leaves? Well, to be honest, I would have hoped for something like that, just because of the variety, but the question is, does the author need it? Did Fujino get enough revenge on Kirito for Asuna cheating on Inoda with him?

Is Fujino really ready to do something different from the cliched endings?
Fujino is already doing "Hero Party Must Fall" on behalf of the cuckold, and then give the cuckold at least some piece of victory or relief? Doubtful...
