30 seconds at the end, based upon what you are saying. That does not meet a definition I have listed - in fact, I was quite clear in my definition and how this is excluded.
vndb has tags which are fan ascribed and voted upon - so popularity wins. Also, I do not find it on vndb - that doesn't mean it's not on there, but searching for "Hajimete no Hitozuma" reveals nothing. It do see the ntr tag on hanime and netorare tag on nhentai.
This is a lot of snowflake. By this very lax definition almost every "cheating" / "infidelity" where the cheated upon finds out in the end is netorare - and that doesn't delve into feelings at all, it's more like a jump-scare in a horror movie than actually creating an atmosphere of fear, suspense, helplessness, etc.
I'm not going to argue against it anymore and simply agree to disagree.
