So I've played through more endings and overall I like them with the exception of the, I think you call it the disillusioned ending. The one where he just dumps Nozomi because he got no challenge from her.
This ending feels like it needs work. The first question I had is why didn't he just hypnotize her to offer a bit of push back? In fact he could have spent the last 3 months tweaking her to be everything he wanted her to be, only to then become the dog who caught the car. He got everything he wanted, so now what? Maybe upon getting everything he wanted, he realizes that he didn't really want this at all.
A further twist of the knife would be if after 3 months of messing with her head, he's made irreversible changes to her brain, and the old Nozomi is now gone. And perhaps he's both too guilty and too cowardly to face what he's done and that's why he dumps her.
An even further knife twist is if he later spots an article stating she attempted suicide, but its left ambiguous if she succeeded.
Just my thoughts. Overall I really like the writing, but I think this ending could really stand some fleshing out.

Funny you should say that the Disillusion ending is the worst: it's also one of, if not *the* oldest. It's rarely seen updates, as Angela has preferred focusing on new content over re-writing old stuff.
Which strikes me as a good plan, because as the game changes through production fixing and re-fixing older content to keep it up to date with the latest changes will add a lot of extra work that ends up being cut in the long run.
