About the additional content in the other stories. There is nothing about SSP told. Just the past of some characters, so no risk of NTR.
Concerning the warning messages, there is only one, and I added it because some people took so badly a certain scene that I was threatened very seriously. So in order not to hurt anyone, I added this message.
If those additional stories show or mention sex scenes with girls that the mc of the main game has sex with then it is in fact canon and ntr.
The only person we care about is the MC of the main game, past sexual adventures of girls in the game aren't needed or wanted.
If you made a follow up game and it would show all of the mc's harem now breaking up with him and starting a new life with a new guy that would not get the initial game the ntr tag, but it would still be canon and ruin the game just like the last of us 2 ruined the last of us 1 and the same goes for prequel stories.
You already saw that people don't want any kind of sharing/ntr after that sharing render you made, don't repeat the same mistake again
