They might not notice if a man is already taken, if it's a human woman who took him, thus leading to NTR happening anyway. The way monsters can tell if a man is taken by another monster (or at least has had sex with one recently) is by alterations of his spirit energy that are left by contact with demonic energy, but human women don't have that effect on men. Since the monsters tend to view unattached compatible men as free for the taking (raping), and that after being taken the man is their husband, him returning to a human woman would be seen by monsters as cheating on them. By the published rules of the setting, human men who are happily married to a human woman might not be considered married by monsters, since they lack the 'tag' monsters leave their claim mark with.
