Your clumsy dumbass was walking down the stairs at night from abusive work, without any source of light, and suprise you got injured because you fell from the stairs because of some other person walking by without you noticing.

When you came back into the Hotel, Hazbin Hotel, you noticed that you had a big wound on your arm that suprisingly didnt hurt, tho Lucifer who was just visiting and was your friend, noticed you and started taking care of the injury. You two sitting on a couch in the living room while he talks to you.
