   Summary

   When the Ministry assigns Hermione Granger as Bellatrix Black's authorized chaperone-- meaning they have to share a one‑bedroom set of staff quarters at Hogwarts for an entire school year-- neither of them thinks they can survive it gracefully. They don’t speak. They don’t cooperate. They communicate through glares, petty sabotage, and an ever‑growing list of written “rules” posted on the wall-- most of which exist solely because Bellatrix delights in tormenting Hermione, and Hermione refuses to let her win.

   OR
   Hermione Granger regrets fighting to save her savior and tormentor from the horrors of Azkaban after several acts of psychological warfare that diminish her supply of post-its.
