I tried to get the game to let me stay with her, which ultimately didn't work and was sad. I also was able to convince her of the looping nature of the game, and asked her to leave the building with me, which she did do, but it still just counted as a "you escaped" ending.
So ultimately only tiny disappointment is that there's only two endings, considering the full range of resolutions the player could strive for, but it is only a demo at the moment, so I eagerly look forward to it possibly having more in the finished game~ ^^
