We All Fall Down

This is the story of my OC Avery who lives in the world of Hazbin Hotel. (If you haven't watched it already I highly suggest, but it's not for kids.) Any characters that come from the actual product of Hazbin Hotel are the property of Vivziepop, not me. However, I probably won't be using any of the canon characters in this. This is just for me to have some fun and relax, so don't expect too much out of this.
Avery has died and gone to Hell. Obviously. He's handling himself just fine thank you very much. He has certain rules he follows. 1: Never tell anyone your real name. 2: Don't stick around for too long. 3: Don't talk about life before Hell. 4: Always sleep with a knife. And 5: Don't take up an offer unless it benefits yourself. However, despite all of that, Avery finds his rules crumbling when he comes into contact with one other certain demon. They'd been in Hell together for the same time span, but are only just now meeting. Can this demon get Avery to open up?
