I was excited for this from the moment you announced the project! The idea of an AI molded to be someone's idea of the perfect wife against her own wishes is just really interesting to me on a personal level.
And it did not disappoint! The visuals and UI were amazing, and the voice actors did an awesome job. It was a compelling story about a woman keeping her own identity and free will (or not) in the face of an abusive relationship, and all 3 endings were vital to diving into the theme.
(This will contain spoilers.)
First, the Woman ending! I was so happy for Yumeko when she finally escaped her metaphorical box after escaping her literal one. The topic came up in the comments below about whether the Doctor really should have died, and it's an interesting topic. I'm inclined to read his death as a more symbolic rejection of the life he's trapping her in than any insinuation that people like him literally deserve to die, but I could be wrong. It seems a little beside the point. If an abuse victim opened up to you about their past and how they wish their abuser were dead because of it, you wouldn't tell them they shouldn't wish death on people because it isn't nice, would you?
Yumeko gets to be her own person, though the journey probably won't be easy. Which brings me to...
The Wife ending! What I love about this ending is it doesn't blame Yumeko at all for making this choice. She has a darn good point; yeah, she could escape, but...then what? Where would she go? I think this acts as a rebuttal to the "Why doesn't she just leave?" argument often made about abuse victims. One of the other comments mention women who don't know their rights or how to get support. I specifically thought of woman trapped in marriages where they're financially dependent on their husbands. While at first glance, you'd think leaving is the "correct" choice...I don't think either of them are right, or wrong.
But I think the ending that resonated with me most was The Statue. First off, it's very impressive visually (the gradual changes to Yumeko and the UI were great). I noticed in a response to one of the comments how you compared the Doctor's programming of Yumeko to Pygmalion's sculpting of Galatea, and I love how well that fits. When you sculpt a block of marble, you can never add to it. You can only take chunks of marble away. And that's exactly what's happening here!
(As an aside, that's something that interests me about the ethics of the Doctor's actions discussed below. Where does "creating her" end and "mind control" begin? Is an unmodified DAHLIA template sentient? Would that be considered her true self? If not, at what part of the process WAS she her true self? Not the point, but fun to think about.)
The main thing I took away from this ending was: if you had the perfect partner who always agrees with you and never does anything you don't like, they wouldn't be a person! You might as well just be talking to yourself. The only reason the Doctor couldn't just have imaginary conversations with a life-sized doll is because dolls can't cook, clean, or take care of the kids.
Overall, I really enjoyed this. Thank you for giving me the opportunity!
