The Demon in Apartment 4B

We follow Lumina, a young star burdened by the weight of her mother's expectations and haunted by her past, as she moves into a new apartment seeking freedom and a fresh start. Things turn around when she gets in contact with Alastor and the two make a deal, a deal that brings about problems for the both of them.
