A character with this trait engages in netori, which is the act of "stealing" somebody else's significant other, a very close friend, or in some cases, a close relative. It doesn't matter how the character achieves this or what his intentions are. Netori could be achieved through seduction, coercion, blackmail, outright rape or other techniques. The trait does not describe "stealing" someone's unrequited crush or a potential hero(ine) on a different route, as the the close ties between the partners and their forcible separation is important to the netori/netorare fetish.

It doesn't necessarily mean that the loved one is literally stolen, but the negative feelings experienced by the one, whom the significant other is stolen from, might make it seem so.

Netori/Netorare is more than a simple act of infidelity, but the fetishization of jealousy and other negative feelings commonly associated with it. The one who loses their loved one almost always finds out about the situation and suffers from jealousy and the feeling of helplessness arisen from an inability to change anything. The one committing netori and/or the stolen loved one might rub it in by humiliating the loser in private or in public.

Please apply the (Subject of) Netori trait to the character whose romantic partner was stolen from them by the Netori, and (Subject of) Netorare trait for the character being stolen.
