"Will the protagonist be able to keep his job, will his beloved girlfriend remain faithful to him? It depends on the player..."
then in the Dev Notes:
"The story focuses on brutal female domination, cheating, betrayal, cuckolding. Not everyone will like it. Be careful and do not download this game!!!"
Looks like it's NOT up to the player LOL, The description in the OP makes it sound like MC can save his relationship...then this is in the dev notes. Might want to be more clear in the description or NTR haters are going to flip the fuck out.
Edit: I hope when they finally pull their head out of their asses here at F95 and finally implement the NTS, and NTI, tags that they also find a tag to differentiate between a passive cuck who likes humiliation and femdom and a normal cuck who just likes to swap and share....most of us have rules set up where the partner can immediately veto people like this bully.
