Strawberry Blonde counts! As I said, that's just a personal preference, auburn, copper, ginger, natural red, strawberry blonde, all work for me. Not sure why the clearly dyed don't quite hit the target, but I'm just one person so that's me from the peanut gallery.
Just finished what's out, seems like a great start! Solid slice of life vn. Characters are well defined, and also intriguing. Jenny has that combo of Type-A control/career gal thing going, but is also sex forward, pushing past her boundaries and/or has an exhibitionist kink. But still worried if MC will judge her about it. Nikki has a bit of a Tsundere vibe, with some mystery/tragedy implied in the backstory and is probably on the adult streaming side, like on OnlyFans. Eva is a bit more on the shy but still very into sex side of the spectrum (caught the Afternoon Delight comment, and volunteered discussing wet panties). All of the ladies seem very sex-positive overall. The writing seems high tier (though a few grammar sweeps will catch some fixes), though one small critique would be the pacing of the sex scenes seems to be on the very accelerated side of things. Not sure how much is hyper-orgasmic ladies, time-compression, or just brevity, but they felt a little truncated to me. Really solid start, excited to see how things go forward. You've got a great little game on your hands Dev.
