Try not to think of it like that. Ignore the ntr route completely. If you didn't know that route existed, you would never think that Lauren would be capable of doing such a thing. And so, Because you take good care of her, she wouldn't, and isn't. In real life, Just about any girl who might like you, isn't going to keep liking you if you don't keep showing her love and respect, and thus will eventually ntr you, maybe not with an entire school, but you get my meaning. If you take care of Lauren, she will be your closest ally, friend, and lover.
