The biggest strengh of a VN is the writing honestly, several VNs are known for being long, slow and with hundreds of options and interactions with many paths and endings, the sex scenes are the rewards and the climax of such decisions the player made or for crucial plot points or revelations, the artwork in most of these VNs tend to be photoshoped scenes with characters in for technical and budget reasons, most of the effort goes to writting, character design, music and in some cases full voice acting. NTRman chooses a more straightforward approach, with the MC going in one line instead of a sandbox where you can explore, interact with characters and trigger events. This one line approach is good for having more control over the phase if it wasnt for NTRman not giving his projects the neccesary lenght needed. I think the reason why SoL is divided into chapters is so he can made it slower if it wasnt also for the case that instead of one Heroine we have one per chapter so we bssically get back to the same problem unless the options that were blocked in the first chapterd imply you dont necesarily lose your heroines but i doubt people would want to posy a NTR VN where the NTR happens several chapters in.
The question is: Can we wait? There wouldnt be a problem if he slows the phase and corruption progression with the only exchange being he would deliver the NTR once the project is finished?
I think Adelaide Inn worked very good because you basically used your wife as a prostitute from neccesity and the same case can be said about TotD but not right away which added more suspense. And tbf eith Minjee, she already had cheated before before meeting the MC, she wants to survived so she ends up with Nelson because she wants to feel secured and his sexual skills(She is trully a closet whore if you think about it or maybe is just me), the nerd like people said it was due to mindcontrol drugs(i hope we got more of this in more creative ways) and the old man because of a trait, funny enought, Minjee does actually fall somehow in love with the Oldman and unlike Nelson's brutal degradation to her or the nerd's drugs after she comes back from the oldman she feels conflicted.
What i can say, the Oldman does know how to give sex to a woman, specially to someone young like Minjee who probably does not have that much experience compare to him.
