Most of the time "Cheating" is when your character does it while Netorare is when your character gets cheated on.
Netorare is usually done through forceful methods. Cheating usually done with FMC's eagerness.
netorare, guess the uploader missed the giant NTR RPG in the corner of the cover art.
In Japan, NTR can mean either (ETA - see: NTR Legend), as well as scenarios where the protagonist is the one getting taken (which the tagging rules here miserably fail to acknowledge as something that needs to be distinguished from 'just plain' cheating).
Netorare involves the unwilling participation and eventual corruption of the partner (usually a wimmen). Cheating is the partner just actively consenting to screwing behind someones back
