HyruleRL to answer your good questions, Kanza has no Lust points, why? simple to make my work easier, it is in the way his mother behaves that Kanza will be more and more open.
For the roads, I can make sure that Kanza for example does not do anything with Said, the problem is that it will pose me problems in the progression of the characters, in short it will take me more time to release new update (I'll be honest, most of the people prefer to see all the scenes, if I make multi routes, it's just going to complicate my work, for not much).
inkpot to answer your good and nice propositions, for the disperse, it's simple actually, if Radia let Nabile touch her butt on Sunday, she won't be shocked if Nabile touches her waist on Thursday ! you understand what I mean.... ?
And for the message at the end of the content, you're right, but this update is a bit special because it's an update that doesn't increase the Lust which is 82max, so normally the message that says you can't unlock new scenes is when Radia and Nadia are at the beach, but next time I know what I'm going to do to fix this problem.
