It could but it won't happen like that cause she needs to win a fight before....
Before what?? Girl you can't just start something like this and not finish it
Spoiler :
Ayrin need to win a fight against the guy in black who pushed her as a child to create the story....if she win she'll be able to die go to this world and have the imprinting, if she lose she'll totally disappear and her world created.....she will need to live as her real being during 5 years win her fight then die ( Lucillion will be with her all along even if she won't recognize him until the end).
So if the dad kills the other imprint in modern earth then mc's soul gets stabilized and settles in the current world, right? Right?
