Never played Wild Cats, probably will give that one a try.
And I will admit there are a lot of female characters I find attractive or interesting that aren't ever made into a route. I just kinda.. accept it. Take a look within, spot the gooner and say "Buddy.. you have like 9 other girls tf are you doing?"
If I get upset about something I tend to look at the situation and if I'm wrong, I am wrong.
People around here do have valid reasons for being upset, many of which you have mentioned. But in my logical brain(I simply mean my own logic), I believe that none of it should've been possible or misunderstood. Misinterpreted. Whatever word I'm trying to use rn.
Also about Yuka, that's why I said "Not sure what that means". I may think she means "Yeah mc and I are just going to bond, nothing sexual." but then next thing I know dev bends the terms of that and does something that isn't "technically" incest(and she does say "well not technically[not incest]" so my first assumption might definitely be incorrect.)
I'm assuming(if he decides to bend the terms) that there is a threesome of sorts where Yuka "helps" with either Miharu or Chika(one of the two idk, they both seem like plausible picks), but doesn't engage in anything with mc directly.
