Dude, I'm not trying to steer anyone toward it. I'm just on the page people have already steered toward, defending it from accusations that seemed to me petty at best.
I played through the scenes we're referring to again to be sure, and there are a couple things I want to point out:
Neither Ayase nor the MC really won the fight against the thugs. Both were in a rough spot until her backup arrived and saved them. I kinda misremembered this, same as you I think.
After the fight, yeah, she blackmails him after apologizing for attacking him. Nothing disputed, but we obviously disagree on whether that was justified. I still don't define that as a rape accusation in and of itself, because the accusation has not been made. And that's exactly what was said in OP.
I appreciate the apology. Any ad hominems I directed toward you I felt were retaliation, and I'm sorry for them. I think this game has a lot of potential and I saw your criticism as being blown out of proportion. But now I understand that you were ranting from a place of honesty, even if I disagree with... pretty much everything. And that's better than trolling. Hope you will come back to it later and have a better impression.
As far as Chika, I'll probably keep adding points to her route and see where it goes. Like I said elsewhere, actually staying platonic with her at first does this. (It actually reminds me of Jack's romance route from Mass Effect 2.) But she's not best girl by any means. I would actually hope that the MC can end up in a monogamous relationship with her if things go right. I'm not particularly worried the dev will lock the player into anything with her that they don't choose (especially after her mixed reception here). Of course, I can't know what her story will be.
