Honestly, the best outcome would be if everyone actually went on to be more successful than originally. The only thing that makes me confident that won't happen is that, of course,an anime hero can never just enjoy happiness, aka getting Shinoaki as a wife is too much happiness, so of course the author will destroy this new reality. :/
I totally expect this anime to be utter trash, though, and Kyouya just casually killing his own daughter, because he feels his friends from the past are more important. That will be extremely morally wrong on every level, but that's the kind of anime this has been since episode 3.
