The Bride He Chose Was Deadly Revenge

Thorne, the last pure‑blooded dragon, is frozen after having his heart ripped out by vampire Count Felix. Five years later, he is reborn with a heart of ice, disguises himself as a bride in a marriage alliance, and infiltrates the castle to seek revenge—only to be doted on as a “substitute for Thorne.” Torn between love and hate, he nearly kills Felix, but triggers a memory flashback that reveals Felix was under demonic mental control and had only ripped out his heart and frozen him to seal a demonic rift and protect Thorne. The misunderstanding clears, and they join forces against the instigator Damian and the demon conspiracy. After life‑and‑death trials, they resolve all old grudges and stay together to safeguard the continent of Charlie."
