No, there won't. We don't like NTR either
NTR is a complicated term because it means like 3 different things depending on *what* kind of NTR you mean - in this context I think the original question was asking about netorare, which is when another character steals the main characters love interests - in this case MCs. NTR is a blanket term that can mean very different things, for example MC + Leslie from the view of Paul is netorare, but Paul's not the main character, we (MC) are, and from our context it's still technically NTR but it's the netori version - where MC (we) steal other people's love interests. It's more about power than jealousy or shame in our context.
