I wouldn't say she was fine with it. Every time the store owner added to the menu or even 1st suggested it. She was clearly against it. With her opposition becoming stronger as it continued. But she had the backbone of 1 ply toilet paper, so she folded. And by the end, looked like they stopped asking and simply forced the issue. Even when we as the player requested her services. I believe she was always reluctant with every option. Outside of vaginal at the end. But that was more so her finally getting to choose the person. Been a time but I believe it was implied. That she viewed sex as something shared between people who care for each other. Hence her begging for us, the one she grew to like, to be the one to take her virginity.
Sure, she's first against it, but after that her mood stabilizes, and not into a resigned misery, but into a "this is fine" kinda state. All that would be fine, and I didn't even question it in earlier patches, but since then it was confirmed that she has a bunch of clients, which makes it weird how can a pure hearted girl like her be so fine with servicing multiple man a day.
Also, my suggestion of turning her into a slut would work better for the conversation she has with her sister, when she's forced into offering anal. I mean, just because her sister is teasing her about her dildo, she agrees to fucking random dudes. How the hell does that make sense, if she's supposed to be shy and pure?
What I am confused about though, is how the dev didn't see this coming. People wanting to help and/or save her. Or generally not liking what happened. It's not like this game is the average smut on here. With a laundry list of fucked up debauchery at the forefront. It's a game of love saves the day, with a man and his android. At least so far. So how they thought this was just going to slide by is... weird.
That was weird to me as well. Like, does this dude not understand human emotions/behavior? If you make a cute and kind character, then put them into a shitty situation, of course everybody will want to help her!(with the exception of the ntr fans) Maybe he thought people wouldn't care so much about her, since they would be preoccupied with Ako's content, but that only applies if you develop your game at a breakneck pace. Even then, once the game is finished, people would just look through all the side activities and find her anyway. So it's a real headscratcher.
Maybe he actually expected people to like her, just not this much. That seems like a reasonable interpretation.
