There had to be a fallout sooner or later
This just proves that the nexus has to be the most fickle entity in existence. Following this, she's discovered that she somehow managed to pick up an entirely different novel to the one she took with her, and now she's sitting in her room, red faced to beat Usagi on her best day, and trying to figure out a way to get back to the nexus so she can return this to waterfell. Because really, this is just beyond embarrassing. And she wants her own novel back too. So romance isn't a subject she'd be interested in normally, but hey, she's always willing to try new things out, and her missing novel was definitely interesting.
