It's something that would make me sick in my life, but it's exactly the kind of plot as a "bad" ending that I wouldn't mind seeing in the game.Well, here's the concept of the game. In fact, as players, we should understand that Kirito should feel the maximum loss if he stays with Asuna. Asuna is already a whore and can snap at any moment. They should be in a relationship and even get married (for Asuna to sleep with Inoda at the wedding, lol), that's how it works.
Let Asuna fuck with Inoda, and Kirito with Suguha and Sinon, the main thing is that we see that Asuna and Kirito are still a couple, even if nominally, but if they are both convinced of this, that's enough.
Regarding the different paths. There are enough bugs in this game as it is. if the author had made different paths, the players would have constantly fallen into other maps and hung up. The author just chose the main path for the plot and does it. It is ok. But we get regular updates. Otherwise, someone with an alternative path might not receive any content at all for this update. Who needs it? So enjoy the game further)
