Seraphina, a once-wealthy heiress fallen on hard times, signs a humiliating contract to settle her family’s crippling debts. By a cruel twist of fate, she discovers the cold-blooded kingpin behind the underground loan ring is none other than Elias—her refined, restrained literature professor from university. By day, he is an upright, erudite scholar; by night, a ruthless devil who traps and dominates her. The two become entangled in an immoral, charged power dynamic rooted in her debt repayment. As old family vendettas erupt into violent bloodshed, their twisted game of control takes an unexpected turn. Lines between victor and vanquished blur, and neither can tell where manipulation ends and genuine longing begins.
