   Summary

   ***Please read the tags for each chapter!!

   This starts as a Female Zayne X Caleb slash. Mentions of Zayne and MC before the accidental sex change. Then turns into a lot of fighting before becoming a Male Zayne X Caleb X MC pairing. I may even add on a Female Caleb X Male Zayne chapter.

   Simone and MC are conducting research with Zayne using their evols at a molecular level. Zayne is given an accidental sex change. Zayne only trusts Caleb to take care of him during this time.

   "I have no idea. I mean, sexuality and gender and sex… they're all just parts of an equation, right?"
