I thought the backlash was because of the dream/memory segments that depicted other men?
Although this still doesn't count as NTR since the girls aren't being shared or stolen from the MC. Since the scenes depicted were part of the past.
The only NTR was the netori. MC taking Mary(?) From her ex husband.
That too, but on other platforms the optional lesbian content was also critized as being sharing/NTR. *shrug*
Some people out there are of the opinion any depiction of any sexual contact with anyone else than the MC automatically makes it a form of NTR and "not harem anymore".
Even if it's optional and entirely (and easily) avoidable.
The mere knowledge of its existence appears to already be a problem for some.
