There is (apparently) a subtle distinction between NTR and cuckolding. It seems NTR (short for netorare) is when a Male humiliates another male by sleeping with second males woman. Cuckolding is when the Woman is the instigator of the liason.
This seems to be the current "correct" parlance, But in reality netorare is quite commonly used to denote any situation wherein there is an intent to humiliate or demean the current partner of one member of the liaison.
Is not really like that. NTR (Netorare side) is:
When main character suffer all the pain. An exemple.
MC is in love with a girl, girl is also in love with mc. But a bastard man steal you girl, so you girl start to do sex with this bastard and little by little, she start to like it. Than the bastard find a way to let you know, that he is fucking you girl. Ofc you girl try to hide the betray, but all the time Mc find out. So Mc start to cry, suffer pain, chuckolding and other shit.
In the end, the story becomes an absolute huge shit. I really hate NTR (Netorare).
But NTR do not mean only Netorare. NTR mean also Netori, that is the reverse thing. In Netori you the mc steal all the girl form other guys that is much better.
The gift reloaded is both Netorare and Netori. In some way when you pick the correct answer you steal girl to other so, you are the bad boy XD but better to be the bad boy, that the chockolding boy =.=
