Erwin Smith

Eren us homeless. He sings in a subway for cash. One day Erwin hears him. Erwin runs a bar and grill that turns into a Nightclub on the weekends. Erwin offers Eren a job to sing during the week. He gives him a salary, room board and one meal a day free.
What happens when Eren joins the staff? A bar tender hell bent on keeping everything clean. Bouncers that are big and scary looking, a cook who may have equine ancestry and a mad scientist who concocts specialized "drinks". Is this a safe place for Eren or a Circus he needs to figure out?
