I get what you're saying but maybe the main audience feel tricked that this was basically either a scandal or studio interference, or whateva? I don't know and don't care. Karen Kaede is not on my rather. Neither is the other Karen lol
We all know porn stars play different roles, we also know some fans are wayyyy serious about their idols.
We also know Japanese fans tend to spend lots of money on videos and merchs from their idols.
We know JAV actresses and studios take fan complaints seriously.
It a good system. Keep your fans happy and they will lovingly spend money on your stuff and adore you
