Dowon has spent his entire life scraping by at the bottom of society. So when his soul is torn from everything he knows and thrust into the body of Lee Dain, a wealthy and heavily pregnant omega, survival takes on a whole new meaning. The problem is, the original Lee Dain was a creature of privilege and cruelty, arrogant to his core and dripping with contempt for everyone around him. Dowon, who has never known comfort, let alone power, cannot fake that kind of malice. Every instinct he has screams at him to be humble, to be grateful, to be quiet. The mask he tries to wear is a poor fit, and it begins to crack from the very first day. Hankyung, Lee Dain's husband, watches the shift with sharp, suspicious eyes. He knows the man he married. He knows the venom that used to live in that gaze. But the person standing before him now is different, softer in ways that make no sense, and yet carrying a quiet, desperate strength that is entirely new. Once, Hankyung loved Lee Dain. But something happened, something that turned that love to ash and filled Lee Dain with a hatred so deep it poisoned everything between them. By the time Dowon arrives, their marriage is a cold, hollow ruin, held together by obligation and the child on the way. Now, as Hankyung begins to notice the cracks in the facade, he is forced to ask a dangerous question: is the man he once loved truly gone, or has someone else entirely taken his place? And if so, what does that mean for the fragile thread still tying them together?
