Just my opinion, but for anyone thinking of starting this game...
Don't bother.
1) The only way to progress the main plot is to subject yourself to the Blonde step mom's abuse. So far there is no path forward that doesn't include being her submissive.
2) The whole Mia subplot is idiotic and completely ignores the MC's existing magical resources. Once he understands the situation he should be able to utilize the lovely invisible ladies at his disposal to learn everything that can be learned about "Denzel" and cut this whole plot off before the first intercourse scene where both he and Mia are unwilling participants, leading to grateful consensual sex with Mia, but nooooo... for some reason we have to completely ignore any of MC's other resources.
And when the MC does think to use those resources? Someone decided to steal a little bit from Spiderman no way home and advertise his new game in the process...
If in later developments, there is a way to skip this entire game sequence, great, do that.
If not. The developer has decided getting people interested in his new game takes priority over keeping the plot of his current game in tact. And screwing over the teacher Mia by making everyone forget who she is, is just wonderful, ain't it.
