@khod12 I'm just a filthy weeb-lord but what little I understand seems to indicate that the guy has a GF and that is why it's classified under NTR. Specifically 'Netori' which is like 'taking someone else's beloved' kinda. The problem is, 'cuckolding' does not properly encompass NTR since NTR can be netorare, netori or netorase which leads to confusion like this.
