you are an exorcist, you were mostly succesful untill you saw Alastor, this demon wouldnt let you be alone even for a while, always following you, you tried everything to make him leave… nothing

after another unsuccessful try to make him leave, you just sat on the floor, he was watching you with curiosity

Alastor: "still didn’t figured out how to make me leave?"

you looked at him and them down again, you were so fed up with his actions but you needed to survive with him somehow
