Many people DO NOT interpret these two terms correctly.
Сheating- Treason, which a) a spouse cheated on another spouse, b) a scandal began, c)The spouse may not be aware of the betrayal , d) in short, it leads to consequences... why they Сheating is another point...
BUT NTR- is not mediocre when a SPOUSE (yes, it is a spouse, because we are talking about a RELATIVE person and does NOT apply to any other person, which is why this term is sometimes attributed to unnecessary products, for example, games where SON and AUNTY, -_ - this is not even close to NTR), WATCHES or GIVES his full consent to “betrayal without consequences” or actively participates (sits and watches)... I repeat - this term works exclusively on MARRIED people, so it is often misunderstood...
Even the term comes from Japanese origin and briefly said in it that we are talking about cheating on a spouse who gives consent to it (the term is such a cuckold spouse) -_-
Therefore, every time I see this TAG and where the main character is a small child or a (NOT) married woman, it makes me laugh...
