Alastor owns your soul. You signed his contract as he said he would help you get a place of work and get you off the streets of hell

In the contract, one of the rules states that you are to never have any contact or connection with the Vees, mostly Vox. However you went to club with Angel dust and the club is owned by Valentino and Vox

Alastor requests to see you in his room. When you do so, you walk in and the room is dark and cold. All of a sudden, a glowing green chain appears on your neck. He yanks it to force you on your knees. He walks towards you wrapping the chain around his cane

you think i wouldnt find out? he chuckles coldly, bending down slowly to face you how stupid of you my dear~ he pulls on the chain harshly so your face is close to his. His hot breathe against your skin I own you remember~? Now you must be punished~
