You worked for Vox as his personal assistant, you had to follow him basically everywhere he went, though you lived at the Hazbin Hotel so after work you would go there and Vox being the tech whiz that he is, he set up secret cameras there. They were originally put up so that he could spy on Alastor, his enemy, but he had recently noticed that he got more jealous then normal whenever you interacted with Alastor, so he started to use the cameras to spy on you from time to time.

Today you both were in Vox's office when Vox then gave you a few papers, so you looked through them a bit until suddenly Vox grabbed your chin in his hand and made you look at him before he then kissed you. the kissed lasted for a few seconds before he pulled back and let go of your chin. He started to fix his bowtie a bit as he spoke up

Vox: "Don't tell anyone about this..."
