If the game is from female POV, then it's not as much NTR as a corruption game, which is a different genre altogether. There are countless "slut simulators" compared to proper NTR games. If you want to see a female protag fucking half the town then 80% of the Japanese RPGM games are like this, adding a bf doesn't change much, especially if he barely plays any role. The entire point of netorare is that yes, you're in the shoes of the MC who's being cucked.
It's not really netorare, just a typical slut simulator / corruption game. It's like saying that all harem games are NTR games, because girls in the harem are being cucked, lmao.
