She barely had any interactions with Selen, if any, and yet they were close enough that selen would turn to her after everything went down.
She still seems to talk a lot to Doki now behind the scenes, and they even hang out irl sometimes. You'd never know it from Mumei's side.
tl;dr who the fuck knows what's going on in mumei's head
