Sacrifiqué Mi Alma por Su Gloria

Ella, a lower-class girl, deeply loved the noble Kyle. Back then, to help him regain his territory, she made a pact with a demon with her life in exchange for an undead army. Afterwards, she deliberately pretended to be materialistic and heartless to leave. Six years later, she changed her name and lived in hiding, raising their son alone while bearing an abyssal curse. Kyle, deceived by Isabelle, believed Ella had betrayed him and repeatedly humiliated her.
