And what about Ziva and Grug? I know, she isnt MC's girlfriend more like fuck buddies, but still.
And what about Shakalas wedding night?
So like in real life.
Ziva & Grud
No NTR. She is not in a relationship with anyone. We also have to encourage her to do the scene.
Shakalas wedding
Also no NTR. She is married to us. However, this is a cultural custom of the goblins. And she won't be stolen from the relationship either. It's not even cheating because the MC agrees to it. Strictly speaking, it could be cuckold. In that case it would be netorase, which has its own vocabulary in the western world and is therefore not considered NTR either.
Whether it is NTR or not depends on 3 questions:
1. Is there a relationship? (it doesn't really matter if the MC is involved or not, the relationship counts)
2. Is cheating taking place in this relationship (or willingly sharing in the case of netorase)
3. This event has a negative impact on the relationship? (or a positive in case of netrorase = willing opening of the relationship to others)
If the answer to only one of these questions is no, it is not NTR. Quite easy to understand. If people want to understand it
