Transmigrated into crown prince Blake's wife within an R-19 romance novel, Ancia confronts a haunting fate—in the original story, his bride abandoned him on their first night, leaving him traumatized and cursed. This time, she refuses to disappear. Blake, the second male lead, presents himself as a monstrous prince concealed by exquisite beauty, yet reveals himself as a desperate, lovesick boy with an intense attachment to her. Diana, the true heroine, wields the only power to lift his curse. Ancia's mission is to become his sanctuary and step aside when the moment arrives. Blake has other plans, however, pursuing her with possessive devotion. "Ancia, don't leave me!" he cries endlessly, desperate to keep her by his side.
