Human Slave Turned Out to Be Succubus

A devoted orphan named Iris escapes her cruel employer when a dangerously charming stranger pulls her out of the situation, only to discover he has bought her outright. Bound by a magical contract, she learns that she is not human but a succubus, and that whichever demon captures her heart and body will take the throne of Hell. Two demons pursue her and both declare their love, yet one of them is deceiving her, and the cost of finding out who may be enormous.
