Very simplistic to dismiss all criticism of the upgrade contents with the most extreme versions of reaction to it and pretend it's all fine.The problem here is people...not her character, not her backstory and not the way she is written. Usually the same people who can't handle the fact their favourite waifu has fucked someone else before them and isn't quite as pure as the driven snow as they would like. Let's be honest, you see it everyday on this site in pretty much every thread lol. Like seriously, people need to get a grip, though we all know how fragile many people on this site are. Maybe they should just stick to things like MNF instead, probably much more their cup of the proverbial tea.
There's multiple angles to it, and multiple people reacted differently to different aspects of it. Yes, the discussion has gotten stale around it, but it's been many pages, and people have pointed out plenty of different issues.
1. Shift of personality (togs himself says Kiki was never planned to be like that so that people notice this jarring shift is hardly surprising)
2. The joke about fucking builder dude right away not being well delivered
3. The inability to define your precise relationship / and her behavior
4. Her backstory, in different ways
... probably more; didn't really all of the quite stale debate either way.
For me, it's all about how it's presented. Neither the protagonist nor Kiki act like people to me. You can compare them to Lois, or Kara - and how long that took for actually anything to develop. There was some attempts to make it like people interacting with each other, getting to know each other, and then ramping things up. But for a while now everything seems incredibly rushed.
Kiki is just the most extreme example. When you ask her why she feels like becoming a slave, and she reveals that she was date-gang raped, and the protagonist basically goes "cool, show me your tits" (and also possibly "let me grab that footage") ... that's just ... words fail me how anyone could think there's no problem with that.
It's not the background. It's not the character. It's certainly not the reader. It's absolutely definitely how it's written.
Had she mentioned 13 updates ago that past decisions got her into trouble. And had she then slowly build a rapport with the protagonist, and perhaps along the way revealed some of the tragic consequences of her actions, and had this then slowly developed into the relationship as is now few people here would be talking about it (yes, some people would always complain about that backstory; it's noise, filter it out...).
Instead, again, it's completely rushed through. Protagonist comes across as some sort of inhumane, uncaring monster, and what Kiki needs is therapy, and not ... whatever this is supposed to be.
But whatever. It is what it is now. Update pressure will probably ensure that these things keep happening.
