That's what I was wondering too, especially since the butler mentioned the doctor advising against her using it again. I'm thinking the VR was her escape, but her high sync rate could've made her disability appear within the VR world as well? Like she started experiencing weakness in her lower extremities
She is !!! Novel readers actually confirmed it as soon as she made an appearance ^^
I haven't read enough to get her complete backstory, but my guess is that she became disabled when she was younger. Like Almond, I'm guessing her high sync rate is also due to her visualization of using her legs.
the girl is def jeonjapa right..? was she always wheelchair bound and using the vr as a escape as well or.. is it like a side effect of the high sync rate
