my man how can it be ntr if the image is canonically before the pc and her were together?
That's just a previous relationship, although I do also find it weird that the mc keeps it for his own viewing.
They have been together for 3 years but only she considers it a relationship. She works for a character who makes games in the game universe. Ted has to fuck ghosts to capture it, similar way she having sex with that character capture video references.
I have avoided NTR category for a while now but whenever I receive Newsletter from DLSite this tag is always on top so it may have affected my judgement.
