I don't know where you get that she is canon. There's nothing stopping you from doing what you're saying.
In fact, if you're not in her path, she doesn't even appear in the chapter.
She doesn't have 2 scenes, it's really the same extended scene. It's normal that so far she has more scenes, since you start in a relationship with her (they have to satisfy people who need sex scenes from the beginning), but that doesn't mean that it's focused on her, but you have to meet the other Li first. From now on the content will be more balanced, as the rest of the Lis have started to have content.
