I mean, I just have my doubts for now because Fujino doesn't usually go for a happy MC in the end. It could differ this time as this project is more nuanced, but for now, I don't see it.
I guess the 'not know' ending will be him living on believing everything is fine, but tbh, I can't imagine how that could be portrayed as even closely believable. Inoda is probably living with Asuna and her mom, also with at least one kid by the end. Unless the admin just keeps deleting everything forever, so, yeah, in that case, he will think of himself as a happy dude with a girlfriend who just doesn't ever have sex with him.
On the other hand, kinda a very creepy image if he can never move on because he is in this shuffle... until he dies
