Fantasy, involves the 7 demons of the deadly sins and Lucifer. I believe the FMC worked at a convenience store before meeting demons who save her.

I need help finding a book that involves the 7 demons and revolves around the female main character who is not mortal, and falls in love with the main demon. I believe it starts out with her working at a convenient store, gets robbed and then saved by said demon. Lucifer comes in who she also has feelings for, and the I believe involves some sort of war between the demons and Lucifer (?) fairly new I believe it was published within the last 5-7 years. Help please!!

Do you remember if this was a stand-alone book or if it was part of a series?
