TW- Swearing, Violence, Graphic Imagery When Y/N, a genius scientist, is sought after by the Fatui for discovering the key to their victory, she's taken hostage under none other than The Doctor, Il Dottore. Upon meeting each other, neither can shake the feeling of wanting to know more. Both are controlled by their scientific minds that tempt them to understand everything. What happens when they cant seem to understand what goes on in each others brains? Sometimes science isnt the answer to everything and this time its a matter of the heart. They have yet to understand that and so are determined to get into each others heads. Will this experiment be a success or will it require further testing? * No smut * * Includes headcanons and unconfirmed theories * * All characters owned by Hoyoverse. * *Written before 3.0 so some inaccurate info is stated!! Eg. Dottore is referred to as the 4th Fatui Harbinger when he is actually the 2nd

I couldn't pick one Fatui Harbinger Man so why not have a chance with them all? This book will have multiple routes with different Harbingers.
