Well the dev wants realism ( yea that's why we play games because reality is fun lol , smh)That's a head-scratcher that one I've played a few games like this and not once on a love route have I ever encountered NTR.
Which means that he want the characters to feel real so if you pick Clair,, jenni will move on with her life with others in her own way and vice versa if you pick jenni
The typist said you will eventually control the female you didn't pick thus controlling her in her own life away from MC )
And you know people will consider any guy other than MC looking at the girl to be NTR
Another factor is that he said he loved and enjoys NTR way more than love and his ability to write NTR is way better as well thus refusing harem or win it all scenarios so yea there will be NTR alot of it
Follow discord he is much more talkative/ informative there
