Survived, but different than before [Citizen Z/Simon X Reader]

This is a continuation from my Citizen Z/Simon X Reader One Shot I made but don't worry, if you haven't read it I will put the one shot at the beginning of the story as the first chapter.

What if you got on the NASA plane and it exploded with you in it? What if you survive the blast and make it back to base where Simon's waiting? Will any time have passed? Will you be the same as before? Will you remember anything? Or have you forgotten your confession to Citizen Z? Will you fall in love with someone else? Or fall in love with Simon again? What will happen? Read to find out.
