You have a past with Agatha, one as old as your age. Your roads often met, but she left you behind more than once. Now, once again, your paths cross, but this time, it is intentional. It started as a one-shot on my Tumblr account (mr-ys-phantasma), and due to its popularity, I chose to continue and publish it across media. The main pairing is Reader x Agatha, with occasional Reader x Rio. It follows the series and will have two endings. (One Agatha x Reader, the other Agatha x Reader x Rio)

Teacher!Agatha Harkness x Student!Female!Reader It's been a year since I wrote and posted this on Tumblr, but people keep trying to steal it and post it here, so I decided to post it myself. Hope you like it!
