You could give Ruby the memories of Mason but leave out the soul like when she’s falling through the space-time thing she hits his soul and absorb some of his memories and ends up in another reality I’ve absolutely loved reading this and hope you rewrite it
I look forward to continuing. And as for Mason, then... it can be done so that Ruby's will was initially stronger, and the soul could not attach to her body, but left a cast of memory and a system. Mason himself can still be used somewhere else - in another fic. Let's say he was reborn without the promised system but with an open aura, idk.
