The Netorare tag needs to be removed. The Dev clearly stated that it's not based on his own interpretation of what Netorare is in the games opening. From the Devs PoV, Netorare is only when the cuck is actively being cucked in front of his cheating girlfriend/ wife and not when he's "oblivious" to it. Just the Cheating and Swinging tag are necessary by the Devs definition.
Netorare by definition is just the act of a Significant Other being Stolen. Generally this PoV is the cuck being the protagonist. Whether the cuck is clued in on it or "oblivious" to the acts going on is optional.
Netorase is the closest thing that defines what the Dev is aiming for in this game, as it is from the perspective of the female lead protagonist. Again, whether the cuck is clued in or "oblivious" is optional.
Netori would be from the perspective of the man who plans to steal the girl from the cuck. And once again, whether the cuck is clued in or "oblivious" is optional.
But then again maybe the Dev is aiming for a Netorare tag in the future? Don't know, but still the game looks fine to me.
